if we happen to sit for so long in a coffee shop

I was sitting in the coffee shop pondering... about a presentation I have to make. I was deciding between two quotations. One says, "Life is a journey not a destination." Almost cliche. The other one says, "Reserving judgment is a matter of infinite hope." The latter is from page one of The Great Gatsby. That's the line that stuck with me for some reason.

Suddenly, in the middle of my pondering, the girl next table got up and fell down, crashing at the chair on which I placed my bag. She stood back up immediately before I finished asking if she was all right. "I've been sitting too long," she said, "My legs just gave in on me." I asked her once more if she was all right. She said yes, and I could tell that she was embarrassed and I didn't want to make a scene of it. She sat back down, with her iPod in one ear, looking a bit dazed, as though she had forgotten where she wanted to go in the first place.
