Internet misunderstandings

Have any of you ever done something on the internet you shouldn't?
I recently decided that I was fed up with walking alone trying to achieve some sort of fitness, so I decided to look on line for like-minded people to walk with. I found a site for fitness buddies and duly filled in the application giving age, rough location and a little speech introducing myself. I imagined I would get replies from ladies of a certain age who would enjoy a good walk and chat and hoping to make friends. What I did get was men.. the latest one sent me a message and a ropy picture of himself, he wanted someone to go on walks "and more", whatever that is, and, if I came up to scratch, to "share weekends away in his caravan". OMG lucky me.... I DID NOT THINK. Back to Gransnet I think, so much safer.
