You've already heard about the ordeal I went through at school before, you don't need to hear that again and quite frankly I'd rather not open old wounds again.
So yeah, that is my worst experience.
The best experiences though?
Contrary to popular belief, most people are nice, you just remember the nasty ones more, so the annoying thing is that it's really hard to remember good experiences.
I guess it's probably one of the awesome times I spent with my Grandma when I was growing up (my parents both worked full time jobs so I ended up spending a lot of time with my Grandma).
