Sometimes I Wonder If It's All A Joke?

My ex, someone I used to fancy, my sister and my best friend are out partying. Together.

There used to be conflict with my best friend over my ex. There was also conflict with my ex over my former interest, and vice versa.

Now they are all out having a great time while I, the initial mutual link, is slowly dying of boredom and other things 8 hours away from it all.

HA HA HA HA HA HA Ha Ha Ha ha ha ha ha (?)
