Insects, Rodents, reptiles.
Bees, Spiders, rats, and snakes to be exact. They freak me out!
Self absorbed people.
The people in this world who can't take two seconds of their day to reply to an email or text baffle me. We all get bathroom breaks and lunch breaks, I mean how hard is it to type or text a line saying hey I'm good just busy ya know?
That's all I can think of! :)
