First of all, I am sad that someone down voted this. Shame. The set up is excellent and I respect you for trying something fairly difficult. To make the same letter flow well especially in a short poem, is difficult. You did well here. The emotions are there because you made the readers heart sad. Well done for that. You definitely leave the first few lines up for interpretation. That to me makes for a good poem because it makes the reader curious and wanting to know the answers to the questions. But there really are none. My first thought was a high school student because this happens a lot, sitting alone in the cafe or classroom observing. It seems also this girl has been hurt and that's why she is shy. I loved the message. Simplicity at its best!

Judging Comment:

Now here is a write that is not only written well but
it also holds an image for the reader. The writer
has used words beginning with the letter "S" and at
the same time written it in a way that makes sense.
As for the write itself, it holds a deep sadness that
has been portrayed in a beautiful way. The
loneliness and longing is captured within this write...lovely.
