There is a six-year age difference between my sister and my brother. When they were little, they slept in the same bed...
Winter: My sister woke up from the cold
Sister: Where is my quilt?
Turning around, I saw a mummy brother wrapped tightly.
Summer: My sister wakes up from the heat
Sister: Why was I pushed to the wall?
I turned around and saw my brother sleeping in a big crotch.
Sister: Haha.
So what is it like to have a brother? Answer: I'll steal your quilt in winter and your mat in summer.
