There are just too many postings here for me to read all of them... BUT nonetheless... I would like to give you a peice of advice!! ;) Well Firstly, it is not only your opinion but the girl's too. Age might not seem to be a big deal to some wheras it is of great importance to some people. For instance, if a 27 year guy would have asked me out when I was 19.. I would be totally freaked out. But the good news for you is not all people are same. And she might actually have no preference of age.. BUT your problem is she calls you dai. If I thought some guy was cute.. I would rather not address him directly than call him 'dai'. Secondly... talking to her in a formal way and just smiling at her when she calls you dai will give her no idea about your intentions. If you are just too embarassed to go and tell her whats on your mind take the long way around. Tell her to not call you dai anymore(as suggested by someone before), and give her subtle hints. IF she reacts in a negative manner.. hide your face and do not expect anything back from her. If she behaves positively... it might either be because she wants the same thing OR she is just fond of you as a friend or acquaintance. You will hjave to go to the next level then and be direct with her.. THEN ypu know what will happen! So there goes the advice from Dr. Rythm;).. Wish you all the best. As I always say "Hope for the best BUT be prepared for the worst!"
