Went to Singapore Science Centre today. Learnt and experimented about Heat Shield. After that, went back to school and saw that the Sec 3s were back from Pulau Ubin. On the way back to school, I fell asleep in the bus. Haha. Had band later on. Didn't know why I was so tired today. Got released earlier and had a chat with our Sec 1 juniors. Then went to 'Tropical' to buy some refreshments. Went home with Ying Jie. Walked home from Bedok after alighting from the bus.
