Hiyo,

while I'd really like to know just WHY Timid is considered a Snarky character, I plead to make it a Neutral character or, if that would unbalance too much, replace it with something else, like 'irritable' or 'short-tempered'.
Since English is obviously not my first language I checked and double-checked...but yet

Dicitionary.com gives me this for 'timid':

1.
lacking in self-assurance, courage, or bravery; easily alarmed; timorous; shy.
2.
characterized by or indicating fear:
a timid approach to a problem.

I don't see the connection from timidness to snarkiness...
