I think my first girlfriend turned into the moon
I hope you are just being silly. Why would you ever be lead to believe that?
We both liked the moon and we both felt connected to it in some way.
Thinking about your first girlfriend each time you look at the moon is healthy and a nice outlet, but believing she actually turned into the moon might make people think that you're going a little bit delusional. You should understand that she's not actually the moon.
Don't be so judgmental, lots of people believe different things. Some of us are a little 'out there' but we mean well.
I fully understand that you're just trying to have positive thoughts about your first girlfriend. It's just going to make people think you're a bit strange if you go around saying this is what you believe.
