29. Allowing my friends to drag me to a strip club the night before for a bachelor party. It was dumb and we ended up getting a DUI. My wife was furious at me because I had specifically told her we would not be going to a strip club but I caved to pressure from my douchy friend. She was standing there at the altar in her dress furious at me and trying not to cry during what should have been one of the happiest moment of our lives. I learned a very hard lesson that day.
30. Asking a friend to run the video instead of hiring a professional.
31. Inviting 75% of the people. Most of them I never see and are not involved in our lives. Would have rather spent the same amount of money on 25% of the people and had one hell of a high-end party.
