Dear Lily,
How are you?
I just want to share with you a bit more about the picnic on Sunday. The weather is going to be fabulous according to the weather forecast, it's going be sunny all day. But there will be a lot of people there as the cross country event would be happening. We will be meeting at the gate around 10 am, and you have to bring some food to share with the group.
Hope you will enjoy the day.
Your friend, Li Hua
