Saying I'm tired for the first time!

Today when I was driving, I asked Andre what color/shape is watermelon, he was kind of spending a lot of energy of thinking and trying to putting his word out, as he didn’t sleep well, and was tired. After I pushing him and using candy as reinforcer for a few rounds, he said “annoying”. lol. I was keep pushing him, and then he said “I’m tired“. Hahaha. That was amazing.

今天让Andre想和说西瓜是什么颜色和形状的，他说“讨厌”，然后几轮之后他说“I'm tired” lol
