Ok, I may sound old fashioned, maybe, but I like to get to know people before dating them. It aggravates me when you're pestered with "call me" messages over the internet. I don't know who you are, why should I call you? And for that matter you don't know me, so why would you give out your phone number.
Or those messages that tell you to contact them the minute you get the message. Hon, I have a life, and no offense, I don't like being told what to do.
I don't know, it's just rude.
