Faintly embarrassed smile?

I got some very strange looks setting up and taking this one! Just a simple shot today to show what a good mood I'm in! I booked some great new business for 2012 and treated myself to a quick lunch at a nearby deli. The olives, pitta bread and hummus were delicious - couldn't finish it all and so had a quick play with my food - just as the waitress came to see if I wanted anything else! Anyone else finding that the 365 project makes them chat more to complete strangers, explaining what they're doing?
