My dd, 12 yrs old, got a cold sore today, and she's never had one before. I get them but I've tried to be as rigorous as I could with hygiene so none of my kids catch them from me. Poor dd is distraught, crying, saying she's got them for life now. I think that's true, so I couldn't think of anything consoling to say to that. 
Is it true that she will now be prone to them? They are such annoying things, always popping up at the worst times. I'm sad for her.
