Our parties pretty will dried up around 10 years old.
I would not call hanging out with 1 or two friend a party.

But that is what it done here too. Take a good friend to the show for your birthday or something like it. Or like others said a sleep over. No goodie bags, no games to plan I love it.
My dd found it sad that the kids in her class didn't even do Christmas cards this year or last and she is in grade 5. I asked about Valentines and she said if she didn't get Christmas cards do you really think they would do Valentines. Guess I am done buying those too. Kids are growning up so fast these days.
