Don’t engage with some people. Engaging with them is just like playing chess with pigeons. You’d be concentrating, thinking about your opening and the upcoming moves in respect of the rules. The pigeon just flies in, lands on the board, shits on the Queen and attacks the King with its beak. It then flies away to congregate with other pigeons, flapping its wings proudly while they celebrate its achievement.

Don’t play chess with pigeons.
