Definition of a "gentleman" has seemed to become subjective over time. For instance, I was raised between a ranch and city life and was brought up to respect your elders, respect the opposite sex, respect the Lord, and to respect yourself. The keyword is, you got it, respect. Yet in today's time, I have been told not to call someone "ma'am", have been slapped for opening a door for a lady, and actually laughed at for expressing manners. This enigma just stumps me even more when I see threads/posts saying "all I want is to be treated like a lady", yet when one acts that way - you are brushed aside as yesterday's news.
The problem with "online dating" is you never know what you are actually dealing with. Yet for instances like me, I do not handle the bar scene (too many moronic imbeciles) well and I work too much to actually get out often.
