You meet someone who makes you think, hmm, maybe there might be more to life than just being yoked to the wheel called work. Maybe you should go bravely and put yourself out there again. You remember what it might be like to have someone, you free that energy, the frisson, attraction. He made me smile. And even though you don't do anything, you know that you're still alive and that those feelings you bury deep are still there. No pressure to do anything or to make things happen. You just know.....something.
Or even if you don't, accept the moment, it is what it is. Tomorrow is another day and who knows what might happen....but you just never know right.
