I am deeply saddened that I won't get to see you guys for the rest of the school year. I miss you guys so much and can't wait to see you in the fall. Therefore, it is very important that you take care of yourself and look out for your family. The more we practice social distancing and proper hygiene, the sooner we can get back together.
If you have any questions or concerns, please feel free to contact me at firstname.lastname@example.org. I love you guys and take care.
