Do I Swear Too Much?

Yu-Jin was playing by himself in the bath last night and making up some sort of a story. There were two characters and they were talking to each other. It went along these lines:

"You're a bastard."
"I'm not a bastard, you're a bastard."
"No I'm not. You are."
"You're a bugger."
"No, you're a bugger."

The other day he wanted to go into his room where his aunty and grandma are staying. He couldn't get the door open so he started yelling out, "Open the bloody door!"

But I don't think that I am entirely to blame. Miky tells him off in English also and he can swear in Korean too. Now, that's funny.
