Yeah, I often have similar thoughts while waiting for the bus to arrive. My favourite line is "the world is crowded but i feel alone".

At first this seemed a tad too dramatic for me, especially the line 'because the whole world's out there/while i'm sleeping in', considering it is 'just' a bus stop. =P

But when I read it again it made more sense to me. Oddly, I can relate; often times I have similar thoughts, sometimes during the oddest moments/situations.

Keep writing!
