One of my sons climbs. AND had the nerve to send me a picture of him standing -- with his feet showing -- within inches of a sheer drop-off with teensy-tiny cars waaaaaaaay down below. When the nausea subsided, I informed him that it was really unwise to send me such pictures.
Since that time I have on occasion asked him what he's been doing, and he tells me "going to movies, out to dinner and That-Which-I-Am-Never-to-Mention-to-My-Mother."
