Injury's suck

So today, while I was assisting in the 3-5 class, we were doing their recital dance and at the beginning they put their hands up to their mouths and 'laugh.' (Their song is 'It's a Small World' never do this song, it's extremely annoying.) So I went to do it, cause they just finished learning it so they cant do it alone yet, I bent my elbows and put my hands up to my mouth and went 'Ow!' It turns out, I pulled something in my elbow and I can no longer bend it. Do you know how hard it is to shower, change clothes, brush your teeth, do your hair, pretty much do anything, without bending your arm? Pretty Darn Hard! I had to have my sister put my hair in a pony tail for me cause I'm just that disabled at the moment. It is not fun whatsoever, plus it's my right arm! It is also, I found out, difficult to do a dance without using your arm, or at least without bending your arm.
My grandpa was trying to convince me that not having a thumb would be worse than not being able to bend your arm. To which, I responded, 'I would rather be able to bend my arm and not have a thumb than the other way around cause what use is a thumb if you cant use it most of the time.
