Hmmm. I am going to assume you to be a bus rider, and one with these experiences as well. I am also going to assume you to be much more in touch with reality than many other people. I think interesting that you paid such close attention to something so small. I think its interesting that you wonder what your friends think. I also think you want them to think that you might to prove in any way that they do care about you.
I think it would be a great idea if you wanted to further this and create a background (or even a sequel poem). You could make a collection and tell a story. Just a thought! Loved the poem!
