SS's 10th birthday

Opens presents before permission.
-Says he wants to play video games with his dad and sister - completely leaves me out. Since, I'm not playing, sis doesn't have to play.
-Makes us all go to an expensive Chinese buffet, and gets a plate of chicken and garlic bread.
-Tells us not to fill up because we are going to Dairy Queen for dessert.
-Wants to go bowling, then wants to go to laser tag. When told that I don't like laser tag that much, but his dad will take him and his friends to laser tag in a few weeks, he responds that his dad can drove me home and the rest of them can go to laser tag.
-Doesn't get yelled at or anything for saying that. We all end up going to laser tag. -Whines for another game even after being told no, it's too expensive.
-As with every restaurant we go to, he doesn't eat three quarters of his food then he pushes it on either his dad or his sister. Plus, he's the youngest, but his meals are the most expensive of everyone's. He complains, his dad gives in, he gets his way.
-We go to Dairy Queen, he gets dessert, he pushes three fourths of it on his dad and his sister. Both don't need the extra caloric intake.
-Wants to play more video games with his dad. This time dad asks everyone to play, so we all play.
-Whines for a later bed time, whines to know what the rest of us are doing after he's in bed.
Makes these commands all evening under the explanation of "it's my birthday!" What does DH do? He never said a word about any of the bad behavior and acted like SS was being a saint on his birthday. I hate everyone.
