We had this argument about a million times when we were planning. I was planning our wedding, working and working freelance on the side at the time. I wanted to kill him! I am trying to think of anything that he did for the wedding and I'm coming up empty. He did help me pick the invites. Oh wait I remember! I left him mostly in charge of the music. It was almost a total disaster! The person who was supposed to create a playlist for us totally flaked out and actually even cancelled coming to the wedding at the last minute. Luckily I had already hired us a DJ to run the ipod so we had to change it to him running the music. Then the unreliable friend ended up coming and Dan didn't get the music from him until the DAY OF the wedding! And THEN the iPod died mid-reception. Thank god we already had teh DJ in place who was able to pick up the slack and play his own music.
So the lesson here is maybe if he's totally not interested you might be better off leaving him out of it!
P.S. and if it was up to him we would have been wearing army shorts at our wedding! No, I am not kidding. Yes, he actually thought this was a great idea.
