Ours was hoofing it with an old mailtruck and looked really flushed and overheated. I missed her at the door and ran down the street screaming "WAIT".............................
We still hear from our mailman in VT, although it's been awhile. Amazing what a cold glass of water on a hot day can do for a person. I also gave one mailperson wool fingertipless gloves to wear when it's cold in Maine. Her hands were red from the cold.
