It was only four o'clock yesterday afternoon after the examination meeting was over, so I bought two jin of fresh milk and sneaked back to see Youyou. My mother-in-law heard that it was me knocking on the door, but she wouldn't open it for a long time, so I kept standing outside waiting. When the door opened, Youyou saw me, called "Mama" from the balcony and ran over. I picked him up at once, and he gave me a kiss. My mother-in-law said that Youyou had already eaten, so I sat on the sofa with ease, ready to play with him for a while. Unexpectedly, as soon as I sat down, his little hand came up and kept pulling my sweater. I found it unacceptable, so I made an escape again!
