Answer:
You should start with a greeting like "hello" or "hey". Also, think about what kind of relationship you have with that friend and if you want it to be formal or informal. You should then explain why you've written the letter. If you don't have much to talk about, you can talk about some problems that you're having or ask questions to the person that you are writing to. For example, you can say how much you like or dislike quarantine. Another thing you can include in the letter is a joke or something funny to make the person you're writing to laugh. Some things you can talk about in the letter are: how bored you are, quarantine, problems you are having, or random updates on your life.
