My old person trait is that I think 'ghosting' is completely unacceptable and you owe the other person a face-to-face conversation.
the social media part - I'm so tired of justifying why I don't have Instagram or Twitter to people. They think you're weird if you don't have one. I usually just say I used to have it but deleted it because it was stressful, but I don't think I should have to justify it at all
