This is a great time to get to know someone new, because you'll really make an impression on them of exactly who you are and how you think. You'll impress them with your opinions, your candor, your intelligence. Plus, your mind is really sharp now, so you'll be able to read them well and get to know them even better than you might at some other time.
It's likely that any flirtation you start up now will be fun and grow into something more, but if that special someone decides you're not the one for them after all, so much the better -- you've weeded out one more stepping stone on your way to finding the right one for you. It's much more likely that you'll find the interest to be very mutual. You'll probably find that you have a lot in common with your potential sweetie, but even if you don't, you'll still enjoy discussing all the ways in which you see things differently. Your emails back and forth or your conversations on the phone or in person will take on a bright, lively quality; you'll get into fun, spirited debates that will underscore the passionate, flirtatious energy running as an undercurrent between you.
