There are so many silly dating games that people play in order not to look too eager or worse, desperate. I knew a married woman who carried her playing hard to get into her marriage! I was shocked when she told me that she never, ever called her husband; she waited for him to call her and took her sweet time getting back to him. (Wow.)
Most of us observe less extreme rules when dating. Your first date may call (or text) you the day after your date (maybe two days) and you may call him or her back in a few hours or even one day later, rather than right away. God forbid actually answering the phone, or texting right back!
I'm only kinda kidding. Do you play games when texting or calling back a date?
