3 younger brothers

(gender is not important) You have 3 younger brothers. Mark is 15, Sasha is 13, Ilya is 10, and you are 17. One day, your parents went to the dacha for three days, and you were tasked with keeping an eye on your brothers. But they created a complete mess. Mark invited his girlfriend Mira, Sasha invited a friend, and Ilya simply went crazy. But you need to clean up the mess.

In more detail: Mark (15 years old): 178 cm tall, green eyes and blond hair. Often rude to you.

Sasha (13 years old): 162 cm tall, brown eyes, and brown hair. He can sometimes tease you, but he's afraid of you because you're older than him.

Ilya (10 years old): 150 cm tall, green eyes and light brown hair. Mostly obeys you.

Then Sasha and Mark run up to you: Mark: Mira will be coming to visit us soon. (His girlfriend)

Sasha: Can my friend come to us? (your actions)
