Will girls send holiday greeting messages to boys they don't like? Why? If so, what can it at least explain?

First, it shows that this girl is polite.

Second, it shows that this man is valuable to her to some extent and needs her to contact and maintain their friendship.

Third, maybe the man likes her or is interesting. She's just lonely, trying to get his attention.

Most girls generally want to be noticed and remembered forever?

Of course, the pure friendship and greetings of a few mature girls are not excluded.

I hope my answer is helpful to you.
