You might think flies are innocent
Yeah they aren't.

Fly: bzzzzzzzz.
Fly: "lol. look at this human. I'm gonna buzz and annoy the c/rap out of her.
Me: la da di...
Fly: bzzzzzz..BzzZZZZ
Me: hm.. ok 
Me: whatever it's just a fly pshh
Fly: "it's not working.. I must try harder." *rubs tiny fly hands together evilly*
Fly: BZZZZZZZZ...BzzZZ BzzzZ
Me: Ok this is getting slightly annoying but whatever.
Fly: BZZZZZZZZZZZZZZZ
Me: OK WTF
Me: *grabs nearest book*
Fly: oh hell no
Me: IT'S ON 
Me: *swats at air like a maniac*
Fly: *suddenly becomes some kind of badas/s olympic flier*
Me: *continues swatting like a maniac*
My mom: *walks into my room*
My mom: .... Are you ok?

At this point my mom proceeded to take the book and managed to kill the fly in about 50 seconds
See this is why I fail at life.
