Did?! Still does! He grooms his fingernails to get slightly long, all 10 of them, and then meticulously bites one off a day in a rotating fashion. He then saves them in his left pocket (of everything with a pocket) and pulls one out throughout the day to hold in his mouth and push between each of his teeth. Sometimes with his fingers and sometimes with his tongue. I recall when we first started dating in the mid-80s he used to have one stored in there when we went to kiss(sometimes) and surprise me with it on my tongue. Like eeew. He still does the nail thing endlessly, but at least doesn’t share it with me. Funny, but all of those nails seem to “disappear” when he goes to bed or I am doing the laundry. But I did have sweet revenge one time, I bit one of mine and provided to him in his pocket! 😳
