Zzzappp. There it is. That spark of attraction. It hits you the first time you spot him. You glance at him, quickly scanning him up and down, checking for any flaws or imperfections that might cause you to think twice, but nothing catches your eye in a negative way.
Your eyes meet. You smile.
If he smiles back, you raise your eyes to meet his again. If not, you let your brain move to the next thing on your agenda for the day.
But he does smile back. So now you want to properly take him in, but it would be too obvious now to let your eyes lazily wander across his body. So you allow your gaze to occasionally dart in various directions, trying to piece each snapshot into one cohesive picture, while maintaining eye contact.
He introduces himself. This is your one big shot. Within, your internal organs breathe a sigh of relief while simultaneously tensing at the prospect of you messing this up when you open your mouth.
For oh, tis a merry dance we dance.
