So you think you really need a reason to call the man who literally created you (together with your mom, obviously), and always cared and worried about you, no matter how upset he is? You probably remember all those times you were home way too late and he yelled at you like "This is not a hotel! You may NOT show up any time you like, young lady/man!" Though, you know he was actually happy inside that you were back safe. Remember that he was your childhood hero and always prioritized your wishes before everything else.
Please call him, now!
