My family, whenever they'd go to grab something hot, and someone else would say, "Be careful! That's hot!" the response would be, "It's ok. My grandma was a welder."
And the thing was, for a while, my grandma was actually a welder (and later was a uniformed police woman, while my grandfather was an Irish Catholic cop in Chicago, because stereotypes come from somewhere).
So, did anyone else ever use that saying, or is it just a quirk of coincidence that this came up?
