Reason #487 that I love my friends: we make contracts before we go out.
About 75% of the time (and probably more so now that we don't go out as often), we create contracts of random things that have to be accomplished during our night out. It just adds to the fun. :)
I can only find a picture of one of these contracts, but this is just a taste.
Typical things on these lists:
-specific shots to take
-a certain # of pictures to take for the evening
-a song we must karaoke
You get the idea. We have fun. :)
