to go or not to go, that is the question

so, i just got an invitation via facebook to go to an old friends birthday. Sounds good huh?
wrong!
It would be ace to catch up with all the boys again and have a few drinks. but the fact that two of my old best friends , one of which is my enemy and the other who is slightly backstabbing, might be there is putting me off.
Sometimes friends from the past are better off left in the past. There is a small part of me that wishes it was the summer of 2006 again, but then i think if i relived that part of my life, i wouldnt be the person i am today or would i of met the people i have today.
sometimes life likes to creep up on you and bite your butt just to let you know everythings real.
