I don't want to

I do some work in an animal facility and a big part of my work is changing mouse and rats.

So today i was chaning a cage with nice white mouse and there where some young mouse (couple of weeks old) and they never like to get coucht. And also this time one of them was to fast for me. I thought ok let it be i first do the baby's and then the little guy didn't want me to do that so he jumped in my hand. Easier it can't get for me.
