np, I agree. By the time DC is old enough to ride the bus alone, etc., he or she will know what's appropriate as far as sharing goes. as an aside, I was on a plane once with 2 DCs. My then 5 yo dd was sitting next to a businessman who she started chatting up (he didn't seem annoyed -- I could tell he was a dad). I couldn't hear the whole conversation, but at some point loud and clear I hear DD tell the strange man, "and sometimes my daddy sleeps on the couch with just his underwear on."
