Hey! Come On In!

I am not the brightest crayon in the box. The deadbolt on my back door was broken and there was a guy here to fix it. I was running a few minutes late so since he was going to be 30-45 minutes...I decided to take a shower while he worked. I know, there is a stranger in my house, getting naked might not be the best plan but I locked the bedroom door...so the guy who fixes locks for a living surely can't get in, right?
