Genre: a short message inviting someone to a healthy activity
Hi An,
Would you like to join our gentle walking session on Friday? We will meet by the school library at four and walk for about twenty minutes on the safe path around the grounds. Wear comfortable shoes and bring water. We will begin slowly and stop if anyone feels unwell. You do not need to compete or keep up with a faster group. Ms Lan will supervise, and you can ask her about any access needs before the session. Please let me know by Thursday so that we can plan the group. I hope it will be a pleasant way to take a break after lessons.
See you,
Quang
