San Francisco natives seem to be heading to different places. Someone you're dating may no longer be around the following week. Hence, don’t your guard down just yet, unless you want the heartbreak. It only means more dating adventures for you down the line until you meet "the one."
With everyone being so busy and always on the go, the only way you could ever maintain a proper relationship with someone you’re interested in is by texting. As hard as this would be for traditionalists, it's nice to keep communication lines open and keep the romance up even when you're not exactly far apart from each other. It may also lead to some rather interesting situations *cough* sexting *cough*.
