>>86798941Think about it like this: what are children making when they make imaginary friends?
Friends. They are making friends.
This is the part a lot of people seem to leave out when they talk about how the Foster's universe works (and indeed the mentality behind real life imaginary friends). A child who makes an imaginary friend is focused on making a FRIEND, not just an imaginary creature. They expect their imaginary friend to be their buddy through thick and thin, and are willing to treat them like they are real (which in the real world doesn't manifest as anything at all, but in the Foster's universe lets the friends become actual tangible creatures).
As we age, we stop being able to make imaginary friends because we focus more on the "what" instead of the "why". I mean christ, people in this thread wouldn't want to make an actual imaginary friend, they'd want to make a real-life version of a waifu so they can fuck it. That's not a friend, it's a sex object, and being an object it's counter to the point of having an imaginary friend.
That's why the friends have such bizarre and varied proportions, because it's tailored to what each child likes to do and wants out of their friend. Wilt is tall and likes playing basketball because that's what his kid liked to do and wanted someone to play with. The imaginary Frankie that Mike made was probably less because he wanted to fuck Frankie and more that he was lonely and latched on to Frankie being nice to him, even if it was just general courteousness as per the job (we've seen this manifest before with Goo: she was lonely, so she made lots of friends with the shared purpose of "being Goo's friend").
So while it is POSSIBLE for an adult in a creative field to create imaginary friends, it's highly unlikely because adults know that the creatures they're making are fictional and that they'll never seriously treat their creations as living beings.
