Tommy's family (SBI) Doesn't really have - or rather make time for him.
Techno would always be either studying, doing a project,or in his karate club,
Wilbur was almost always playing guitar, doing homework, or talking to Niki,
and Philza was either on an adventure, at work or helping wilbur and/or Techno with something.
But never Tommy... They never had time for the youngest child.
so Tommy distracts himself with his imagination, Creating a version of his family, who make time for him, play his games, and let him come along with whatever their doing
I just love EchoFlower5 and her 'Tommy Centric Prompts', what's wrong with that? And yes I am using another prompt from EchoFlower5.
