I like a girl. She knows I like her. On my birthday, she sent me a message wishing me happy birthday. I said I was glad that you remembered my birthday. She explained.

According to my experience, I know that she remembers your birthday for several reasons. 1. Because when you are good friends, after all, good friends are different. It's normal to think of something about you. Because I am beginning to like you, but I don't know if you will like her. That's what women do. If she is, you like her too. Then you have to take the initiative. After all, women are not very active, so as men, we should take the initiative. Because it has a purpose, after all, women are unpredictable. Who knows if she has any other ideas, so it's up to you. 4. It is to test you to see if you really regard her as a friend. 5. Deliberately teasing you.

However, this is what I usually observe. It depends on your observation.

Hope to adopt
