When walking to the bus stop, I said to my 4 year old, "It looks like it's going to rain."
"Do you have a roof?" was his reply.
I was totally stumped. "huh?" was the best I could come up with.
"I mean do you have a hood?" He was talking about my jacket.
A hood for your jacket is kinda like having a portable roof. I guess it's all in how you look at things.
