What if?

I look up and there you are, casually camouflaged in between the crowd. But I know you notice me, and for a moment we just look at each other, feeling that time freeze. Then with a sense of elation I flick my hair, and turn around. My eyes close, and I take a deep breath as I try to hide it. I know you know that I saw you. And you know I know that you saw me. And inevitably the sense of unspoken words just burns in the air, increasing the pain every second. And I know it's my fault but I don't understand this feeling because I am just sure I made the right decision. Seeing you hug her made wonder though, what if?
