write a poem for a stranger

Give yourself just 10 minutes... you could be on a train, sitting in a cafe, waiting in the departure lounge at the airport, killing time somewhere...  Set yourself the challenge: write a poem, no time for editing, look around you for a subject or a theme... could be that woman over there, her head in a book... or that guy in the ill-fitting suit, or maybe a balloon drifting above the antennaes and satellite dishes, or... something else.  Put it down, craft a poem for that time and place and hide it or leave it for all to see and find... write 'stealthpoets.blogspot.com' so the finder of your little work of art can contribute.  Tell us what it felt like...
