One of the FlyerTalkers whom I hold in the highest esteem
was only ten-years old when I first met him on FT. I have since then met him in real life several times and was even more impressed with him each time, and I am old enough to be his grandmother, almost old enough to be his great-grandmother.
If you enjoy the people you meet on line, you will probably enjoy them in real life and they will enjoy you. We are all a pretty adventuresome lot.
