I'd say they're acclimated

It's been another pretty nice day around here today, reminding me of a story Cate told about a warm day earlier in the week.

Robert was daring to go outside without a hat or gloves. It was a really warm day, up to about 40 when it was all said and done. Cate was telling him he needed to finished getting dressed to go outside.

"After all," I was told, "it's 30 degrees out!"

Robert gives a quizzical look at Cate, and says, "minus?"

Robert clearly knows the difference between 30 and minus-30 degrees.
