After swimming, I sent Mj to her Kumon. Then I went out to pay my water bill and deposit some money in my savings. I returned to Kumon to fetch her but she did not finish it yet. So I sat down to one of the benches there and read my book. After a while, as I feel so sleepy, I took a nap in the corner bench as some of the mothers were also sleeping. I was resting for like an hour when suddenly I woke up with a little pain in my chest. I wanted to continue sleeping, I did not even gotten up because I was really so tired but later I feel so uncomfortable anymore. So I got up, I hope this is nothing or maybe I am just so tired why I feel that unusual pain, well, anyway after a while, it went away. But I did not feel sleepy at all.
