I did that once with one guy that I talk to to see if he would message me (to see if he liked talking to me too). He did after a day or two, but I wouldn't recommend doing that unless you've tried other things first (same as I do). Can/Have you asked her why she does that? It sounds like she either doesn't wanna talk or is someone who just doesn't say much. A lot of people tend to assume I don't wanna talk or something cause I never have much to say but that's not always how it is...it is sometimes tho. I think you should just ask her and if you don't get the results that you wait then yeah, wait a day or two and see what happens.
