My dad (only child) could not grasp how Mom, myself, and my 2 slightly younger sisters could be screaming & yelling at each other for 10 minutes, then 5 minutes later sitting at the kitchen table laughing & cutting up! (it had/has to do with getting it off your chest and not holding a grudge, my dad was very, very good at holding grudges!)
Me when doing senior project hours at a Catholic Church. Since I am lds I am not used to catholic wedding traditions so when they do something I'm not used to, it surprises me therefore I kinda smirk. I feel so bad when I do that. Nothing against the other religion I swear.
