I always get a kick out of the antics of squirrels! They seem so cheeky! I like this British definition of the word: "impudent or irreverent, typically in an endearing or amusing way, "a cheeky grin."" They seem unusually brave or foolish, whichever it may be. They don't appear to back down easily. I remember them being quite close and protesting loudly that I was invading their territory. :)
