I mean, do you regularly check the socials of someone you hate just because their socials confirm why it is you hate them?
Is this 'a thing'?
DH does it with a couple of family members. I do it with two people at work. I'm not signed up to any social media, just what's publicly available.
I thought it was something that everyone most people did but I told a mate about it and she was baffled. And now thinks I'm absolutely mental.
