I was single for some time, so I tried one of these "Dating Sites". After some time of chatting we decided to meet up, the girl I met was no were near as attractive as Her profile photo suggested!
She was actually very un-attractive and turned out to be a different person than advertized! After a few drinks I managed to escape unscathed. I only tried online dating one more time after this, telling the next person to meet me outside a large store wearing a red rose.
So I could take a look before commiting so to speak, when I saw my date wearing the red rose I just kept walking, never to use this kind of dating again. Some people do have success with this system, after my experience I leave it to chance this way works better for me.
