Well, my 8-year-old sure doesn't have that problem... the other day, when it was 95 degrees out, she came out from the bathroom and said, "I just took a COLD shower, and it was the best shower I've ever taken!"
Her lips looked a little blue... touching her cheek, it was cold. Boy, she must have had the water cold! I told her that next time, she might want to take a "Cool" shower instead of a cold one!
