A girl sent a message saying that there is no moon outside your window. What does that mean?

I used to use this trick when I was in love with my girlfriend. I told her that when you miss me, you should look at the moon. When you look at the moon, I am also looking at the moon. Through the reflection of the moon, our eyes can be connected so that you can see me. Isn't it romantic? Although it is impossible to really see it, her heart is beautiful. So, it may mean being lonely and wanting to find someone to accompany you.
