Got extremely annoyed today.
But that's not the word I was looking for.
I had to deliver a case of bottled water to some friends living in another dorm in our college. I have to tell you, the sound of tight plastic rubbing against tight plastic is never a pleasant experience. In any case, I had trouble describing the moment to my fellow friends, and they in turn had no idea how to describe it.
You know, the reaction to nails on a chalkboard, or something like that.
