I enjoy my $3 nail buffer set from the drug store.
It allows me to have clean-looking hands without the need to be dexterous with nail polish. The buffer also allows me to avoid the chemicals in polish. Buffed nails lose their gloss gently and unobtrusively. Unlike polish which sometimes chips or peels or discolors, and often grows out with a definite demarkation.
Keeping my hands tidy is a sign of my respect for those who have to work with me and see my hands every day. Much like showering every day and making sure I don't smell bad.
Existence is empty, but I am full of myself.
