My husband is the one that gets cold sores. Not me. He's had a fair number through out our marriage. I've had zero. When he gets one, he does really well not to have it spread to any of our family. No kisses for a week sucks but hey, no one wants a cold sore! Did you know a cold sore is from the herpes simplex virus? I think they're a pain in the neck and not the most attractive. Like I've said, I've never had one but just recently I thought I was getting my first one ever. I nearly freaked. But thankfully, it turned out to be nothing. Whew! I like not having cold sores and I surely don't want to start!
