>>12290325It's a symptom of severe loneliness and/or isolation.
I'm not even a kid, or a teenager, or even a twenty-something anymore, and I've spend more of my life with someone and around friends now than the years I haven't, but with the current crisis forcing us to be isolated from each other, even I feel the unfulfilled need for companionship, and find myself getting attached to characters in movies and TV shows like I used to back when I was lonely and isolated all the time. So make of all that what you will.
Humans are social creatures and weird things happen when we're isolated from each other for too long.
