A World War 3.
The Dentist.
An evil and non-human entity residing in my home.
Having to endure any more high school than the standard 4 years.
Offending people, even if they deserve it (usually only in real life

. You know what they say about internet anonymity).
Rejection of any sort, this is why I've only had about 4 girlfriends my entire life (the relationships are usually long and "fruitful", though).
Bugs in my room. Not spiders, or ants or anything, I'm talking about big ol' Silverfish, or 3 inch long yellow and orange centipedes/centipede like "things".
Having my mom find my stash o' drugs. I have a great hiding space, and in this hiding place there is a small steel safe (thank you Grandma! You give great and functional Christmas gifts

) with my stash o' weed inside, but I still worry when she hovers around it's direct vicinity, like she can sense it...
Let's see, now... I don't particularly like the idea of being judged. I know that I am constantly judged, because that's the pattern of high school and life, get judged, judge others, but I can't stand the idea of being judged/judgmental.
