I'm not an expert but I'm pretty close at useful-useless knowledge...and yes I mean knowledge that is useful but useless at the same time because it's totally random things I know. That totally contradicts itself but it's true. I know a ton of random knowledge.
I'm like a human jukebox too...I know a ton of different music, the artist, lyrics. Everything from Ozzy Osbourne & Rob Zombie to Glenn Miller Band & Frank Sinatra (my love). My boyfriend is the same way. I can read music sheets like a book too.
I'm also an expert at not lying. I am terrible at lying. So I'd say I'm an expert at being honest.
Oh and of course my favorite expertise...getting away with murder. I went to school for criminal justice/investigation...and I watch tons of shows on it, some reality, some not. And I read a ton of stuff online too. Of course committing the perfect murder is impossible with today's technology but I'm pretty sure if I had to I could get away with murder.
(Well now I couldn't because now everyone knows it could be me if someone came up dead. CRAP)
