Here is the deal; people are not what you imagine them to be.
You see a picture, read a few words, maybe chat online, on the phone, and then have coffee.
Not least of all, our society has become more self-centered and geared on perfection in others making it unfortunate that when we do have a friend that sets us up on a blind date, we eliminate them before even meeting.
All of these play a role in finding someone whom you can build a relationship with but with their decline, we are forced to accept the possibility that online dating is a legitimate means to meet people.
I have been on many dates arranged from online dating websites.
