為什麽不能主動些呢,好男人,即使無意,也會心存感激,絕不會輕視你.

Email him, saying that it was such a wonderful time, he was so helpful, hope will have 2rd chance, blah blah blah.

Attach a well selected Flash(Chinese version), start a topic you two can talk about in the emails followed, or ask his feeling about the trip just ended......

A man like him needs someone to communicate with after work.

Nothing is more horrible than seeing him dating another girl, isn't it?
