When you hit somebody
Have you ever noticed if you are in a fight and you hurt someone with a punch it usually doesnt feel like a hard shot when you land it? It often feels like you just hit a piece of paper.
I always feel like I didnt get them good enough but they react like its a hard shot. When I hit the bag I feel it all the way through my arm but when I hit someone in the face it often feels like I just grazed them.
