My wife and family come home from work and give me leftovers. I got off work late. I haven't mentioned it to my wife either, but I feel stingy when I mention it, and I do it every day.

In this case, you should not submit to humiliation at the beginning. At first, humiliation will make others get used to this phenomenon. You should bring it up with your wife at the beginning. And you put up with it for so long, and suddenly bring it up, and through losing your temper, it will make everyone feel inexplicable and unacceptable. Many times, you should say what you should say calmly. I suggest you have a good talk with your wife and let her leave you food alone every time.
