If someone says you talk nonsense so much, how do you reply?

There are two kinds of people who talk to you in this way. One is your relative or good friend. It won't do us any harm to make a joke or make a suggestion while chatting or talking. Ask them at most if you understand, and if they understand. That's all. The other kind of person is your enemy. They may say such things to you, but they may hate you, ignore them or slander them. We can say, "it's because we saw the crap that the losers said," or "the losers will think that what I said is nonsense."
