I can't be the only one here with a totally gross, 100% pure boy of a FI... while I normally find this very endearing, he has some disgusting habits that I absolutely can't stand.
1) Nose picking - it's like his nose has a magnet in it and the other magnet is in his finger. Especially while driving.... I bet there's a pile of boogers on the floor of his driver's side but I'm too horrified to look.
2) Pulling out the ingrown hairs on his face - FI is half Italian and inherited the dark, thick hair of his Italian side... he has a really nice beard, but a lot of times he gets ingrown hairs. His mission in life is to find these and dig them out of his face at all cost. Most of the time he doesn't even realize he's doing it until I point it out.
