I used to belong to Westfield Sportsmans Club, and I'd take my son fishing there after work all the time. You need a key to get in the gate, which came with being a member. Despite every member having a key, when the range guys would leave they'd always ask if you had yours, so you wouldn't be locked in. It made sense I guess, but it was kind of irritating, as I'm in the "stupid should hurt" court of opinion.
One day I realized that I needed to knock off my swearing when the guy shouted across the pond if I had my key, because he was leaving. I told him we were all set. My son, about 4, looked at me deadpan and said "Jesus Christ, those f**king guys really piss me the f**k off."
A better example of parenting would be my daughter. When she was 3 or under, I was putting her in the carseat and hit my head on the door. I said "Son of a ....." and I stopped, so that I wouldn't swear in front of her. She completed my sentence with "Bis".
Aha - I'm the good guy and I get to correct my wife's language! HAHAHA
I told my wife what happened and what my daughter said. My wife replied "Yesterday I hit my head as well, and I said 'son of a biscuit', so I guess that's what she was trying to repeat."
I guess I'm still the A-hole.
