What should I do? ):

[Fennec]

Okay, so next weekend my entire school orchestra is going on fall retreat. We go camping every year around october for team building and stuff. We're gone an entire weekend, until midafternoon on sunday. But, one of my best friend's birthdays is on saturday this weekend. I won't make it if I go to retreat. A downside is that retreat costs a lot of money, but it is sooo fun. What should I go to? This could be my secind and last retreat at crosswinds because they might close the school next year
