I want to quote a friend's words "what types of friends are you? friend for a reason, friend for a season, or friend for a life time."
I would choose friend for a life time if he or she can understand and forgive my mistake, if he /she is warm hearted, if he/she is decent...
and for this guy, I appreciate his time in meeting me, and his encouragement online before meeting. Actually, I had the plan not being given any feedback afterwards.
But for a guy, he should follow up with an email apologize for his lateness,provide some encouragement and show some kind of appreciation for my coffee just for courtesy reasons. Whatever the busy schedule is, it just takes a few seconds/minutes for correspondence. Anyways, I got nothing.
Life goes on.
