My friends hung out without me and posted Stories about on it on Instagram. How can I manage the FOMO?

Delia Cai and Steffi Cao wonder what to do when you see people hanging out without you.

There are certain social media rules we can all agree on: Ghosting a conversation is impolite, and replying “k” to a text is the equivalent of a backhand slap (violent, wrong, and rude). But what about the rest of the rules? When can we really remind someone of our old Venmo request? What happens when someone tries to flirt with you on LinkedIn?
