A chat on subreddit /r/me_irl

It's also got a trap for introverts and anti-socials like me. I get really frustrated with group chats since I never keep up with them, and to be honest I don't really want to.

So I tried to stealthily leave the group, and of course WhatsApp sends out a message to everyone in the group saying "HEAR YE!! HEAR YE!! THIS PERSON HAS LEFT THE GROUP CHAT👀👀👀"

So they all spam me with messages asking why (meaning I have to socialise more to excuse myself out of the situation) and/or they add me back into the group so I'm back on square one and they notice me again so I have to begin the gradual quieting/stealth process all over again.

Of course, by design when they "invite" you, they actually just add you. You don't even have the option to reject.

Mute the chat, archive it, and then disable "new message unarchives chats".
