imaginary friends are sentient people and everyone can see them

8 years old is considered too old to have an imaginary friend

a large amount of imaginary friends get thrown out on the street legally. At several points they talk about how they had nowhere to go and just wandered around. In Good Wilt Hunting you see a neighborhood full of imaginary friends that live on the street

this is such an issue there’s shelter(s). there’s absolutely political debates about this.

imaginary friends have rights, but not the same rights as humans (they can hold jobs and need passports and such but they can be confiscated/held as property and apparently killed without any legal issues) 

babies imagine abstract, swarming friends, kids imagine normal friends, anyone older tends towards violent monsters that have to be locked up to keep them from attacking people

at one point, someone imagines a friend and eats it because they’re hungry
