Very true conclusion about their is always somone stronger! Very good.
I am big and muscular and I hate being a guest at a dojo because they always use me too much! They say "Ah, he is big, lets use him to see how this works"! Its like they have to try and prove their technique works. It makes me feel uncomfortable when a sensei brings my size to attention. It is refreshing to have genetic diversity to train with but lets not be blatant about it! In fairness, I have to throw them hard for it, hehe!
