Summarize the main meaning of the following joke, no more than 15 words.

I'll tell you one too. . It is also foreign.

I forgot the name of the protagonist. Use a and b ~! !

In an argument. The levels of a and b begin to be equal.

Later, slowly, B's condition got better and better. . A is everywhere. A is going to throw in the towel. But B must be reasonable and unforgivable. .

Finally, B was in a particularly good mood. Because I still see A packing her things and getting ready to go. . And b actually made a personal attack. Say: you are useless like this. I don't even know how far you are from the pig. .

And a walked to b and said without anger or laughter: it's only one step away ~ !
