I suppose you're going to say this is my fault

Last week I was in the bathroom putting my makeup on, and since we all know Mitchell is my shadow, he was in there with me. He was digging through the bathroom drawers, pulling everything out on the floor and he came across an old electric razor of Lee's. Yes, I saw that he had it, and yes, I let him keep it. The thing was pretty much drained of battery power and I figured he couldn't go much harm with it. He wandered off and abandoned the razor a short time later. We went about our day as usual. Until I happened to get a good look at his face and notice that something was slightly different. Upon closer inspection I realized that part of his left eyebrow was missing. Oops! I had a good laugh, told Lee, he had a good laugh, and all was good times until the speculation began. I've had several people tell me they don't think shaved eyebrows grow back. How could this be? They come back when you pluck them. I've sure had to shave my legs more than once in my life, so shaved hair does grow. Why wouldn't they grow back? I know someone out there has had a kid that shaved an eyebrow right? So set my mind at ease, and tell me it grew back.
(This is the best shot I could get of a squirmy toddler, you can't see the eyebrow in all it's glory, but you get the idea.)
