So OkCupid, if you pay for it, shows you when people visit your profile and shows when someone likes you. In this case, usually 90% of the time an HB7 and up is not going to message you first. So I use these two lines...depending on the girl. You get the feel for which on to use.
1. I saw you visited/liked my profile, but you didn't say hi...how rude. lol
2. I saw you visited/liked my profile, but you didn't say hi. You must be a shy one. lol
I usually use number 1 for the girls that put off the confident attitude to make them feel like they are stuck up and lower their Value And use number 2 for the ones that actually look shy (they usually reply with. "Hi, sorry. I'm am kinda shy" or something along the lines of that. Number 2 shows that you are calling them out and puts you at a higher Value, but encourages them to open up a little.
Please put your results in a reply. Good luck on your online game gents!
