People all have feelings, no matter how rich or poor they are. Sometimes, they are sad, and express their emotion by crying. Others, might cry because they are angry or hurt. For example, the poor might cry because they are too poor, and desperate for help. Sometimes, it makes you feel better. The rich on the other hand, might cry because some anonymous people posted some mean and rude words on social media of them. That is perfectly understandable to break down, and let out your troubles. The rich might cry, just because of a sad movie, or accidentally falling down. These little things can cause such an outbreak in everyone, and it is very normal.
I think "Jump" is just using your legs to throw yourself in the air, and bounce is just a smaller version of jump, if that makes any sense.
