Can I be unthankful?

Ok, so after being so thankful this month, I decided that there are things I am unthankful for. But the thing that I am very unthankful for is my absentmindedness. It so happens, that this happens at the most inconvenient times. Well, ok, most of the time. But I was cutting Matthew's hair today and I was just doing the shaving job at the back of his neck. THen I saw his side needed cut some more so I took the shaver and.... whack! I forgot to put the little extender thing on it so it wouldn't cut so short. What am I to do? I feel soooooo bad. I guess it doesn't look too bad if you don't look at it too close, but still. The sad part is, the other side in the very exact same spot had been a bald spot of his ever since he was born, and now we finally got it growing out good. Now look what I did, I made the other side of his head bald. Oh well. It will grow back, and besides, he doesn't care what he looks like anyway. For all anyone else will know, he is the one that got the scissors and did it himself. But no, I will own up to it. I admit, I am not the best haircutter in the world. Thank goodness I don't do it for a profession as I would probably not get many customers due to my ABSENTMINDEDNESS! In mine and Matthew's words, ARGH!!
