Funny Girl

Yesterday girl was standing next to me by the bedside in the late afternoon. My stomach started growling due to hunger. She looked at me with her eyes and mouth opened bigger.
M: What's that sound
A: I listen, I listen (puts her ear to my tummy)
(stomach growling again)
A: Baby talking
M: What did baby say?
A: Grrrr... (imitates the growling sound)

Later in the night, she was so excited again. Asked to listen to 弟弟.
A: 弟弟 never make any sound
M: Why?
A: Just now, 弟弟 say he haven't drink Vitagen
M: Is it? You drank Vitagen just now??
A: (realising she's not suppose to let me know she drank Vitagen) Errr.........bye bye! (runs off)
