I don't know, I don't like the idea of time travelling and I can't think of a time in history that i'd like to go back to, nor would I want to go to the future, I guess i'd just travel back in my past and not do/say anything that i regret doing now
I wish I could go to a time in the past where Alan Rickman (the actor of Severus Snape) is still alive, and send him the fanmail I had been planning on sending him last February.. </3
