Oh, jeez. DS with his hard-core punk Papa had heard just about all the worst songs that I can imagine. Butthole Surfers, Iron Maiden, Dead Kennedys, The Misfits, etc... including many, many that I would be embarrassed to name.
But what can I do? it's his Pop. And he seems to be turning out fine, even if his thinks the lyrics to that old melody go: "It's just an old f***ing love song, coming down in three-part harmony..."
I definitely think actions are way more important than words. No words are off limits in our house, but mean behaviour is never accepted. And while ds is definitely pretty radical, he is very sweet, helpful, honest and pleasant. And that's what is important to me.
I agree with the talking bit, although I let ds bring it up, in case he didn't understand in the first place. He usually says something like , "Oh that's really awful, huh, mamma?" or "oh, that sounds like a bad idea! I would never do that!"
