So his birthday went off without a hitch from her.  I forgot this is her new modus operandi for the most part on the "day of" whatever we're celebrating.  Let me paint you a picture of who she used to be, and who she is now when it comes to birthdays and holidays: 

The old version of mother, 1.0 Birthday Edition: 

• She would either take charge by doing things herself, or be barking orders everyone to do certain things.  
• The first certain thing on a birthday would be to require buying donuts.  This is her thing.  Everyone gets donuts on their birthday.  It's not a horrible thing.  But after I took her keys away, she would be barking orders at whoever to "not forget the donuts!!".  Like, we weren't allowed to have a birthday without them. 
• Every aspect of the birthday would be about her, no matter who's birthday it was.  One thing was that even though she had asked you up until your birthday what restaurant you wanted to go to, she had already picked one of her favorites.  Asking you was just to make it look like she actually cared that you wanted something on your own birthday. Oh yes, she REQUIRED everyone go out to eat for your birthday.  Even though she knows I HATE restaurants. 
• If she didn't plan it, she wouldn't participate.  So, if you picked where you wanted to eat and you all were going out, and driving, she would refuse to go.  If you picked somewhere to go during the day, and she didn't have a part in planning it, she would refuse to go.  Unless it was her idea, and she was in 100% control, she couldn't even fathom how to act on such a trip, so she'd say "Oh, you guys go and have fun!  I'll just stay home on this one!"  I am not sure if it was anger because she wasn't in control of it, or it was just her severe anxiety (something she picked on me for having my entire life).
• The last time we went out with her, it was 2016 I think.  We chose "Famous Daves" for my hubby's birthday and we didn't give her the chance to change the location.  She was NOT happy.  Even though we had just went there with her for lunch and she loved it.  But now, since she didn't get to choose on the actual birthday of someone else, she was pissed.  And the entire time she was bitching and complaining.  She was rude to the waitstaff and just plain grouchy.  We were leaving and she SCREAMED at my husband, because she LOVES to tell people how to drive when they're driving.  And my husband slammed on the brakes and screamed at her back haha!  She deserved it.  She was so fucking assholey the entire night and we made a vow right then and there we'd never go out with her again.  Not to her face, but after we dropped her off.  Then the next day she said "From now on?  I pick the restaurant!!"  I laughed really hard and said "Don't worry about that, after how you acted last night?  We're never going out with you again!"  Then my son's birthday came around a couple months later and she asked where are we going?  Like she hadn't just told me we weren't allowed to pick where to go and I said "How quickly you forget.  I told you on Mr. Brooks' birthday, we're never going out with you again.  And I meant it!"  Oh boy she was mad, but she never asked to go out with us again on our birthdays.  And from that day on, we went out alone, without her.  This year we went to Mission BBQ for my son's birthday (we went a few days ago) and it was the most horrible place I'd ever been in my life.  And I am waiting on getting my refund.  Their food is wretched and it's fast-food style, and cost us around $85!!!!!  What in the holy fuck are they even doing??  We're going to take our refund and go to a REAL restaurant, with waitstaff and actual real portions of food for the price we pay and it won't taste like cardboard.  And it will be the same price, including tip.  But here's the difference between me and my mother: had my mother went?  She would have made a HUGE scene, embarrassing everyone, because she was being duped.  But me?  I was quiet, saved my food to bring home and give to my mother for dinner tomorrow (she has no sense of taste, she won't know it doesn't taste like anything).  Not embarrassing my family is worth more to me than getting a refund in the moment or letting everyone know that this place is more than just a ripoff, it's a disservice to humanity to exist.  
• She tried to make these "traditions" look like she was being nice to you, but in reality, she just wanted an excuse to eat donuts and going out to eat several times a year at her favorite restaurants.
