Hehehe, Most people here know my big one....

-Loud kids
-Rowdy kids
-Obnoxious kids
-Screaming babies
-Self-entitlement-obsessed parents
-People who tell me how much they "hate" reltiles/bugs after I've told them about my belived pets.
-People who share with me stories of killing reptiles/bugs after I've told them how much I love them.
-Hearing "you'll change your miiiiiiind"

Oh, and a biggie: When people say "poisonous" instead of "venomous". SNAKES ARE VENOMOUS, NOT POISONOUS! Frogs=poisonous, snakes/bugs=VENOMOUS!! *Explodes*

Erf....I should Stop now....Hehe...
