We’ve all got that friend, right? The one who shows up half an hour late, but they are busy so it’s fine! The one who spends an entire evening talking about their issues, even when you called to have a chat about something that’s been really bothering you. The one who cancels plans at the last minute, because their partner has made plans for them so like, that’s totally fine right? WRONG. Why do we all have this friend? And worse, why are some of us that friend?
