As a dad I care about the subjects my kids care about, so I’m able to take a genuine part in their (almost completely online) lives.
This is why I have a favorite team in League of Legends, a game I have never played.
Right. Sometimes you just have to develop an interest into things you normally don’t care about to have something in common with the people you love.
And sometimes you just should care that your easily influenced teenaged kids are totally invested into content that glorifies and populises severe eating disorders.
Even if you don’t give a fuck about some avocado guy, these are the topics you should listen and talk about with your kids, to help them develop a healthy opinion and viewpoint of things like that. That’s actually a parents job.
