Could it be any more embarrassing than going out to the dental office waiting room and saying, "Hi, I'm Heather. I'll be cleaning your teeth today," with a HUGE lower lip covered in an outbreak of blistering lesions?! I think not. I just kept my mask on the whole time. Don't want people afraid that I'll give them herpes.
NOTE TO SELF: when you spend an entire week on the beach and you cover yourself from head to toe with spf 55 every two hours, don't forget your damn lips.
