When it comes to flirting, you cannot afford to be shy today: life is too short for you to hem and haw and worry about being too aggressive! If you don't step up and let someone know you're interested, another person could beat you to the punch. Preserving a false front is a waste of your energy: so fess up when you feel special feelings toward someone. It's the only way you're ever going to find out if they have special feelings for you too.
