When I was about ten or eleven, I somehow mixed up the words "lesbian" and "leprosy." I used to be afraid of catching "lesbian" after that. One day I overheard my mom on the phone; she was talking about some woman she knew who was a lesbian, and I freaked out and started screaming at her to get away from me because I thought she'd picked up "lesbian" and I didn't want to catch the disease too!
Needless to say, I felt very silly when my mom explained my mistake.
