One of the best things in life
is being is a super loud and busy coffee shop.
You can hum the song stuck in your head at a moderate volume
without looking like a ******
who hums moderately loudly
in public place.

One of the worst things in life
is having a serious conversation with someone you respect
and discovering they have a quite visible ****** in their nose.
Do you let them know about it?
Awkward.
