Hahaha I love it when you used "okay". I'm back to him and he stared at me with no words or excitement when I entered the house. He looked really sad and didn't know how to respond. We hugged very long quietly and I took out some books I got for him. Then, he was back to his bubbly self, finally. Now I realize when he is sad, he keeps really quiet and it heartbreaks me.
Thanks a lot for coming by @amymya :)
