Pina wrote about words today and it's strange because that's what I wanted to include too, words.
When we lived in London on the tube they had poems reproduced on the walls, from current and years before, written by various travellers. They've started to do something similar on our trains here in Melbourne. Two displayed on the wall of the carriage I rode in on the way home from work today read as follows - I wrote them on the back of my ticket.
Mind your feet
under the concrete
and the other
Between me and the moon
leaves only fence posts
Are they haiku's - I forget the criteria for one and I'm too lazy to look it up!
