While riding the subway to work, I took the time to clip my toenails.
That's disgusting. You really clipped your nails on the subway? Why?
I hate being on the subway and the people on it. So, I wanted to punish them.
Clipping your nails on the subway is disgusting for everyone around you and not the right thing to do in public. Save your grooming for when you get home.
I'm going to be gross no matter where I go, so the subway will do.
What you do in your own home is nobody's business but your own, but when you are in public, you need to be respectful to those around you. Clipping your toenails is a gross thing to do in public and will bother people. In the future, you should bring a book to read or some music to listen to in order to pass the time on the subway.
