DH has just come home annoyed. I asked what was wrong and he said he'd bumped into another parent from school and she commented on how tall DS was. DH said to her "I don't know where he gets it from because I'm not that tall and neither is my wife" so she replied "ah, but how tall is the milkman?" and laughed. I know she was only joking but am I being a miserable cow to be a bit annoyed by it?
