Have you ever found a bruise on your body and had no clue how you got it?
That happens to me all the time. I have one right now on my left knee. The one on my left thigh just healed so it must have been time for a new one. Can't go bruise less for too long now can I?
It looks awful, like it really hurt when I got it. But I have absolutely no recollection of hitting it at all. I was going to post a picture but I couldn't get a good one.
How can I not remember something that must have obviously caused me pain?
