I check in by telephone from a hotel room last night and my wife tells me she was cleaning an upstairs room with our ten-year-old daughter while the three-year-old played off to the side and maintained her own running dialogue between make-believe characters. When one of the characters announced she was about to do something (not sure what), the three-year-old said, “Well, have at’er!”
I picked the phrase up from my Dad. Have now – apparently – passed it on.
