Of course you didn't. That isn't how friendships nor relationships develop because you have no idea when you first meet someone; yet that is what so many people try to do on these social networks. Rather, there is a much more natural and slower process. Often it starts with eye contact. Some people will smile back; others will look the other way and ignore you; and occasionally you'll get the "what the hell are you looking at?" evil stare in return. Just the response to that initial contact could make a big difference on who you choose for friends, and who you dismiss. It starts there, you get to know the person; some will become acquaintances, others good friends, some best friends, and occasionally a lover in there. But do you know which is which?
If I email you, it is simply to make the cyber equivalent of eye contact. If you initiate contact, I'll treat it the same way, as a glance indicating a potential interest to know something more about me, but no preconceived implications beyond that. What happens after that? Only time can tell.
Most of my spare time gets consumed spending time with family time, doing stuff with my teenage daughter, and playing pinball. There are a lot of other things I enjoy doing, but just haven't done much of recently for one reason or another, but I'd be game for re-acquainting myself to them. These include hiking, cycling, geocaching, swimming, day trips, dance clubs, goth clubs, swing dancing, alternative 80's music, tropical islands, tiki culture, happy hour, poker, horse racing, comedy, burlesque shows, and some board games.
However, don't let my personal activity set limit your interest. I'm also looking to explore new activities, rather than doing the same things that I have been for the past many years. If you have a fun activity and looking for a companion or partner, I am interested in expanding my horizons.
