Ever forgot you were in a Kingdom Hall and just blurted out a curse word? An old buddy of mine was telling me some story about water skiing and I just said "That's so f**king rad". The elders wife standing a few feet away from me looked completely mortified! I turned beet red.
Also another time I was playing badminton with my girlfriend and an elder and his friend saw us and asked to play doubles. I'm a little competitive so when he blew the final shot for the game I yelled "WHAT THE F**K!?". Realizing what I had done, I apologized. He told me that him and his friend were going to go play singles for a while. Ouch.
