At home. I can listen to what I want to listen to instead of whatever the other person wants to talk about. It's also way less expensive, and I get to use the stickers/decals I like.
I prefer regular nail polish, but there's not enough time to let it set properly, so I've gotta use UV gel or dip powder. I have both, but I have not had the time/energy to use either in the past several months.
