Well, I should say that the charge came up as "OurTime.com" (50+ dating)
Ok, well, that's a lot better than an escort service.
Interesting, though - although he's the right age group for it, most MLC guys at 63 would think they're too "young" for a "mature dating" site.
As you said, it's possible that he just made a curiosity purchase, or that he's really out there playing the field - or maybe he put up his profile and got scared off by all the 80 year old women trying to hook up with him? Who knows?
