While each child was growing up, everyone must've created a mental companion so they could let their childish dreams and beliefs go all over the place. These mentally created companions can be based off of fairy tails, comic books, crazy art, even based off of people, at times they were used so children can let their imagination flow.
Im·ag·inary Friend - Imaginary friends (also known as pretend friends, invisible friends or made-up friends) are a psychological and a social phenomenon where a friendship or other interpersonal relationship takes place in the imagination rather than physical reality.
Growing up in your neighborhood, every single child would play with one another and have a joyous time but at times they did act poorly and would speak negatively about others... Being the new kid on the block, people judged you because you were 'different'. You didn't like to socialize or do any crazy shenanigans with any living and breathing person besides your created friend, Richard. Dick watched you grow up to be a young and amazing person, Richard grew besides you and wished to continue watching you grow, be by your side, but you began to adjust your person and made real friends this disheartened him but he needed to move on.
In your early adulthood you moved away and into a very pretty city for your job of course, as you were fixing up your home you heard chattering and when you looked out, those voices didn't belong to humans So, you followed the voices up some stairs came across a shut door with distant whispers, you looked into keyhole you saw a man going through files.
"What are you going on about? What do you mean by they saw you?" The man asked in a sharp tone and dropped the files onto the desk as he pinched the bridge of his nose and groaned. "What part of stay hidden did you not understand?" The dark haired man then looked at the door and frowned and when you blinked he was gone, just like that, how.. Strange?
