How do I even manage these things?

I have a bruise on the pinkie-side of my right ring finger, and on the palm-side in between my index and middle finger. It's probably the result of two days of reverse knife-hand strikes to Tony the Dummy, but those aren't actually parts of my hands that make contact with anything!

My right knee is also bruised to heck, but that I at least know why. These things tend to happen when you spend a solid ten minutes tossing your teacher on his butt (actually back) with a move that ends with you landing on your knee.

We did a lot of takedowns today, because I happen to ask about the one that we learned at yellow belt (which is what the other person in class today is) and so he got out the mats to practice it. I actually know quite a few now, and so we also practiced front headlock, which was not the one I was thinking of. When I mentioned that, this conversation ensued:

Master Paul: Which one are you thinking of?
Me: The one with the leg sweep.
Master Paul: *thinks, can't quite remember which one that is* I think that was one we just did for fun one time.
Me: Because we have an odd definition of fun around here.
Master Paul: You're just now realizing that?

Also, it's hard to takedowns with someone who is obviously afraid of falling, because they tend to crumple instead of going down and doing a proper breakfall. Which means no matter how good your form is, it ends up looking wonky. Also, it's not good when the person you just tossed off of you can roll and get up faster than you can. Kind of defeats the purpose. (I'm the one getting tossed and rolling, not the one who can't pick myself up fast enough. Of course, I also learned very quickly to pull my knees to my chest to keep from getting kicked while down, so...)

But seriously... what the heck did I do to my hand?!
