I have to travel with my dads side of the family to my cousins graduation and i dont really want to go?

Well they called me up and asked my brother and i if we wanted to go to his high school graduation and we said yes just to be nice well the truth is its not that i dont like them its that i just dont know them that well,(mom and dad got a divorce when i was like 2 ) i spend most of my time with and around my moms side of the family, should i go or not i mean its just a graduation.

Don't think of it as being just a graduation. It's possible that your dad called you not so much as for the graduation, but to spend some time together.

Look its not the end of the world if you decide to go. But, if you don't you just might miss out on something really cool. Talk to yo your dad and ask him about the family, who is closest to your age , their interests are, and so forth. Besides, have you ever heard of the interned? There you go, get to know someone before hand. There is really no excuse in getting to know someone on the other side of the family, they might know someone else that can relate to you. Try not to hurt your self in thinking about the worst just think about the fun you will have and the new relationships that you will forge.
