Stop treating me like a baby mum!

So tonight my dad is not home. He went to Suzhou to have his annual physical examination. I come back to my parents' apartment to spend the weekend. After watching TV together while chatting with my mum, she suddenly asked me to sleep over with her... I felt embrassed and jumped off the bed.

"Nah, I gonna back to my own bedroom."

"You haven't slept with me since a long time."

"..."

"You are my baby, right?"

 Come on mum, I'm still a baby in your eyes, except for the fact of 25 years older!
