These aren't actual relationships. They and us?

We're both resorting to a lesser realm, called fantasy, because reality is off-limits to both them and us.

Our objects of affection don't get harmed when we move on to a young ballerina, or to some badboy actor. The gymnast doesn't get heartbroken, and neither does the poofy blow-dried hair boy singer. Heck, the boy singer replaced her poster of a horse stallion. Nobody asks the horse if he feels rejection.
