Senior sister is ill at home and wants to send her a message. At the same time, ask her something, what should you say about it? How to say it properly?

Say a little courtesy first, and then ask about your illness. Pay more attention to your health and care. After all, you are a senior, and she will help you if you are in trouble. In fact, you don't need to say anything about your illness, just express your true feelings. It's best not to send messages and call to say hello. Text is hot because it is too cold. To be tactful, speaking more and practicing more will help to improve oral English. If you ask something, if the other person doesn't say anything, don't pursue it and keep a good relationship. I may be wordy, but it should solve your confusion.
