What are you passionate about?

Last week, my cousin's families showed up and we all went to a tourist trap. One of them is my age and we've never met even tho our families are very very close and this is the only reason i went for because i have no other cousin of my age in the whole family. So we reach there and meet up. My mom knows i hate these kinda places so she immediately introduces me and her to each other. We shake hands and thats it. Next 5 hours. Nothing.
.
You know like she had a group with her brother and the other cousin. And first 10 minutes i was like maybe i should go and talk but then i said fuck this shit, i aint gonna ruin my already ruined day over these assholes. So i pretended i am having the time of my life. However, i did sneak some time with my uncles. That was fun (i know them since my childhood). So yeah, 5 hours and we head back and on the way my mom says "you should stop acting all mature and all." Well that happened and i just wanted to vent.

In short, fuck the new people. Let them break the ice.
