Excerpt from this article:
Gather ’round, class! Today our lesson will be about all the things you should not do when attempting to hit on a woman online, as told through a single OKCupid message.
DON’T see on Twitter that a girl has an OKCupid account, then explicitly search for her, then admit that that is a creepy thing you did.
DON’T admit to Googling her, even if that is another creepy thing you did.
DON’T act overfamiliar…
DO consider that you’re sending an email to a real human being, not a mythical creature who can only be wooed with the proper combination of insults and cyberstalking.
