You know when you manicure your nails and you use that file thing to scrape under nail tips? Well, my friend, during lunch today kept doing this (without a file thing) but scraping under her long nails with nails from the other hand ..just stomach churning..and then she would kind of flick it off...like I said, stomach churning. I didn't actually say anything as didn't want to embarrass her but ...ugh ! Soooo aibu for wanting to give her a bit of a poke ?
