so on the 7th of July there'll be 2 concerts I really want to see. question is, which one will it be? Green Day? (at Ahoy) or Coldplay? (Gelredome)

I'm inclining towards Coldplay, but it depends on whether or not I win the tickets on ebay, and if any of the others want to watch coldplay. I'd feel terrible if I went to watch Coldplay after promising the others that we'd go see Green Day.

what to do!
