How to deal with those who are all constellations?

Ha ha ha ha, have you ever met such a person? Just like what happened to me. Such people are boring! Later, someone taught me: I kept asking him the same question about constellations, and whenever I saw him talking about constellations there, I asked him questions, which made him feel bored. Later, as long as he saw me, he stopped talking about constellations. I suggest you try.
