With our activity approach, I'm now writing to invite you to join us. Here are some detail about it.
The activity will be organized to a farm from 9:00 a. m. to 2:00 p. m. the next Sunday. What we had to do is to gather together at the school gate at 8:30 a. m. We are expected to pay a visit to the farm first. After that we will enjoy picking vegetables by ourself. We also have the opportunity to look after animals for a while, without that I will be disappointing because of my passion for animals. Knowing that you're really into nature, I believe you will definite have a good time.
I would appreciate if you could participate in the activity.
