This is meant to keep men who are interested in girls from sounding too desperate or like they have no reason to live other than to text message. Even if men are interested and canít stop thinking about the girl, they should show a modicum of self-discipline for a change and not appear too enthusiastic. Otherwise, men may scare off the girl with over-eagerness or the appearance that they have a weak and low-action life. A good rule to remember is to take time with your responses. If she responds right away, that's a good sign, but don't send more than one per response.
