I invited a girl to the cinema yesterday, but she refused. Why didn't you reply to my message today?

Boys ask girls out, obviously you want to chase her. Even if you say it's just a friend, it doesn't make sense, but I tell you from my experience that I was thinking that if I promised you, you would think that if I gave you a chance, you would pester me. I'd rather not give a chance, lest you pester me. This is to tell you directly that she doesn't like you. In fact, you know, why do you want others to explain it to you? Do you think there is any hope?
