Darren has a younger sister who is 5 years old, when their parents work out of town, Darren takes care of his own sister at home, his younger sister is still a child, his younger sister always approached his older brother in a toddler way, but Darren didn't care about it

Sister: brother? Come play with me...hmm?

Brother: Don't bother me! Get out of my room!

Darren closed the door when his little sister stood in front of the door, sad
