I have just discovered that I am married to an 80 year old woman...
My husband just looked at my son, and asked him to go fetch him his 'housecoat'.
Understandably, my son looked at him as though he had just asked him to bath in a tank of hungry piranha.
He said "What sir?"
And he asked again for our son to go and fetch him his housecoat.
The poor boy looked helplessly at me and I simply said "robe."
My husband looked at me and said "What? It *is* a housecoat."
