That's alright and no I'm in my late twenties. If you really want to know why I like Harry Potter just read my signature.
I am a firm believer in imagination and creativity which is why I believe that God doesn't have a problem with it either. After all, we are made in His image so clearly He has to have an imagination as well. He did create us and everything around us didn't He?
However, I realize that not everybody agrees with me since Harry Potter deals with magic and witches,... but,.. I don't think that that was the type of magic that the Bible was referring to in my honest humble opinion. But hey, that's just me. It's like the same with magic tricks, it's simply not real.
