I saw a site years ago, and it may still be around, called "It's Just Lunch". It was for people to meet in a non threatening way for lunch.
Funny thing happened to me, I was on a grief recovery site, having lost my wife, and a lady there asked me where I lived. It turned out she had lost her husband, and lived about 40 miles from me. We agreed to meet half way just for lunch, just like the website.
And now for the rest of the story.....
Kayelle and I will be celebrating our 13th anniversary this November.
