The house you were born in is your future. Whatever you saw there, it will turn to be the source code of your future actions. Pretty much your destiny.
Some bad experiences might be turned a good outcome for you. You used them as a stepping point. You had learned to keep your feelings to yourself, perhaps not even acknowledging them to yourself. You don’t know what” normal” is because your normal is: Your House.
Your friends? You might have played with them, but you didn’ feel you were one of them because your house is totally different than theirs.
