I apologize, I have a stupid sense of humor.

something like this?

I’m sorry that happened! Possibly he wanted to retain his independence as long as possible or sensed a threat (muggers offer “help” before mugging). It’s always best to ask if you can be of assistance, and a simple, “Are you sure? It’s no trouble,” if declined is enough reassurance without being pushy. If the offer is declined a second time, a cheerful and sincere “Okay, have a great day/evening!” is an unakward way to take your leave.

Honestly, I did as you said, but that didn't stop him from doing what he did, lol. Oh, these old people.

That helping people is an achievement. This is a thankless job, I know.

For me personally, this is much more difficult than it seems: I help people a little with small things on the street or in the store, for example, I sometimes give money if they do not have the necessary amount, but I am terribly ashamed to do it offline, and one funny incident happened; I tried to help the old man, he replied that it was not necessary and he would cope on his own, then I tried again, and he yelled at me.

And on the Internet, it's much easier, at least you have time to think about the answer.

So you're saying that I don't have to worry too much because the brain has enough masculinity to admit its end? It sounds logical, but how it will actually be?

You seem to have misunderstood the question a little, I meant when you know for sure that you are about to die, in a day, an hour or even a minute from a heart attack, for example, or from hunger, but you don't want to suffer from this, you want to make this process easier.
