My very lovely friend of many years suffers from regular cold sore flare ups. She has always been fond of cheek (and lip) kissing by way of greeting. I am sure she knows about when the sores are contagious or not, and feel I should just trust her judgement, but I have at times felt put on the spot when she's approached me for a smooch when the sores are there. I have gone in for a close hug instead. Now we both have young toddlers and I'm really struggling with whether or not to say something to her as she loves to kiss my DC too. I find I'm always doing a quick check whenever we see each other and trying to avoid her kissing her by all sorts of silly and contrived measures. Today we met up and she was heading to kiss DC on the cheek with the crust of a sore still on her lip. I got in the way but now realise it is really on my mind whenever we meet, and whereas I ought to trust that she knows when it is safe to kiss or not, I feel really unnerved and it is blighting my connection with my her. So, how can I say something without appearing insensitive? Because I've never mentioned it before I feel a bit of a fraud. If you were my friend, what would be a kind way to be approached about it? I really value her friendship and would hate to upset her. Any thoughts very much appreciated.
