Personal Grooming
There’s a time and place for everything – you’ve surely heard that phrase before, and if you ask us, it applies to this situation perfectly. During a flight isn’t the time nor the place to be painting or clipping your nails. When you’re sitting on a plane full of people, it isn’t the time for personal grooming.

I mean, where does he think he is? What would he do with his nail clippings after he’s done? We’re not sure we want to know. I can appreciate that long flights might get boring, and you might be looking for useful ways to pass the time, but you have to think about other people around you.
