What are some of your pet peeves?
I'll start with a few:
When people say "Google ______ (whatever)" -- Why does it have to be Google... Just search it.
When my tank glass is clean except for one little water mark running down the side.
When people exaggerate cramped spaces in tanks and liken it to a human staying in a 2x2x5 room (or something similar).
Small pieces of debris on my glasses that obstruct even the TINIEST part of my field of vision. It doesn't happen a lot because I usually have my contacts in...
There are plenty more.
I'd like to hear some of yours though...
