My old person trait is that I think 'ghosting' is completely unacceptable and you owe the other person a face-to-face conversation.
My old person trait is dislike of video-form social media. I consider blaring my phone speakers at max volume disrespectful to those in my surroundings and generally annoying.
Hence why my social media of choice was reddit and is now lemmy+kbin. It's mostly text posts and images.
