Does shy girls reply late to their crush?

I have this shy girl in my class, she sometimes smile and sometimes just being rude to me whenever I talk to her (I'm pretty sure I never be bad to her). I just don't get it somehow. When I texts her, she reply my text mostly around an hour but she being really nice each time she replies. Does shy girls reply texts late to their crush? (assume she has a crush on me here)
