This depends on personal philosophy, but truly being mean to someone implies that they are doing something to intentionally hurt someone else on an emotional level. Therefore, in my opinion, you should never be mean to anyone. Even if someone is being mean to you, and you are forced to react, that does not mean you are being mean to them back, it can simply mean you are defending yourself if you have no intention to hurt that individual.
No you should not cry

Yeah. If you really mean it , i mean it's good to know that someone wants you to be safe when you travel.
their look. not to be mean, but if someone weighs more then they should, their looks tell you.
"What is eating you?" is the same as asking someone "What is upsetting you?" - should that someone be sulking or appear annoyed.
No.
Say no, but don't be mean about it.
