One thing that pisses me off is when I'm sitting with my family in church, and 30 minutes into the mass, a 12,000 member family walks over, and instead of sitting in the 5-6 completley empty pews near us, they choose to site in our pew. First, if you're going to be 30 minutes late to mass, don't come at all, and second, there are 10 empty pews around us. USE THEM.
