My girlfriend will return to her hometown tomorrow. How should I send her a message and say something tonight?

Your girlfriend is going back to her hometown tomorrow. You mean you two are going to separate. At the moment of parting, you will feel deeply. Then tell her what you want to say to her, so that she won't forget you and depend on you especially.

You can wish him to listen to the weather forecast when he is not around, put on more clothes when it is cold, catch a cold, take medicine, take care of himself and so on. Because you are worried about him here, your health is the capital of the revolution. It's no use making so much money if your body is gone.

Let him know how much you want him to come back here, so tell him what you should say and what you mean from the bottom of your heart. This is a good opportunity, you must do well.
