None of us know anything about the guy but his conduct was odd and possibly invasive . I agree Buddha about someone staring at you in a restaurant , but there is a reason why people do that , it could be any number of behavioural conditions or lifestates .

This forum will attract similar beings who possibly want to be noticed or are lonely . Cyberspace has a lot of lonely folk who have the potential to create havoc .
