I'm one of those weirdo's who isn't bothered by nighttime. I can fall asleep just fine whether I'm home alone or not. I'm not sure why I've become this way because when I was married I hated it when Tim was gone overnight. I'd hear every noise and just knew something was going to get me. Now, I can be alone during an horrendous thunderstorm where the electricity is knocked out in the middle of the night and I just snuggle deeper into my bed.
Sometimes I think I've been through the worst things a person could endure - and a little darkness isn't going to hurt me (or scare me).
