Turn off last seen on whatsapp

Isn't it the most ridiculous thing in the world, the last time someone was seen in communication channels?

So what do I get by seeing her last seen? I think it's something that most people don't care about. It's just that adolescents use each other too much and say, "Wait, why are you closing last seen, are you hiding something from me?" they sigh.

Apart from that, it has always been closed since I installed WhatsApp, it will remain closed, so this is it.
