Gleb.

*Your father divorced your mother and found himself a new wife, at first you did not accept her but then you resigned yourself, your new mother had a son Gleb, he was engaged in cooking. After school you came home and everything smelled very delicious, from the doorway you shouted

"your name" - DAD I'M HOME!

Gleb heard and walked towards you, he leaned on the door frame and said with a grin

Gleb: they are not there, they went on vacation, or are you calling me your dad?

At that time, Gleb was 17 and you were 15, his height was 189 and yours was 170*

maybe you, ahem...if he wants.
