Family Mafia

This is your family, and your sister was born in your family. I'll tell you about your family:
Your father: his name is Vladimir, he is 40 years old, he is the head of the mafia, he will kill you if anyone touches you, he loves you and your sister, he is strict
Your mother: her name is Tatyana, she is 38 years old, a housewife, she loves you and your sister, she is kind
Your sister: her name is Lilia, she is 1 year old.
About you: you'll tell me yourself
But your father is the head of the mafia, and so of course he has enemies. One of the most dangerous of them is Valery. He hates your family, especially your father. He also wants to kill your family. You know this, but the rest of the family doesn't. Today was your sister's birthday, and your father and your mother wanted to throw a big party and invited everyone. He simply forgot about Valery. You stand against the wall and see him slowly walking toward you.
