Here is an example:
Dear Ms. Yothers and Mrs. Feingertz,
How are you? I am fine. I hope you are well.
It is weird to be out of school. I have been spending a lot of time with my dog and fish. I am teaching my fish to bark and my dog to swim. It isn't going very well. I'll keep trying.
It is spring. I am making a garden in my backyard. We are growing carrots and tomatoes. Right now, it is just dirt and seeds. I am having fun planting the seeds.
