I think that this project was fun and an interesting exercise because it made me think about how to make chatbots chatting with users more smoothly and interesting. 

The most fruitful part is debugging for I have learnt a lot in this process. My bot still need to be improve in next version. The next step I should reflect is the meaning of why choose to make a diary bot on facebook, where a place full of memories.

Meanwhile, the conversation also need to be improved. I still need to consider whether this is a right option to create close relationship between bots and human and how to avoid expecting more form a bot.
