when will i grow up?

we went to my grandma's sister's house today. my grandma left right after she ate and said it was because she didn't want to leave my uncle at home alone. he didn't come with to christmas dinner at my grandma's sister's house because he said that there would be too much commotion and so now that i think of it, he might've just wanted to be left at home alone. now, she won't answer my calls and i'm not leaving a voice mail because i hate leaving those things- i think that i sound like i'm high on drugs on my voice mails.
my cousins were talking about all this stuff that happened to them when they were still in school while we were eating, made me kind of feel like i didn't belong because i didn't have any stories to tell because i don't really have any friends that i hung around with. oh well, not much that i can do about that.
my grandma also told me earlier today about a girl (that i went to school with) being pregnant. a lot of girls that i know and are my age have all had kids and have some kind of home. i'm the last one to grow up, this sucks.
