This could only happen in San Francisco:
I was walking out of Safeway when a homeless looking man walked up to me. I was expecting to have to politely deflect a request for money but he caught me completely off guard by asking, "is that linen?" and pointing to my dress. I kinda gaped for a second and then replied,"yes, it is linen."
He then pointed to an equally homeless looking man sitting at a table in front of Starbucks and said, "You walked by and I said you must be really hot in that linen dress and he said maybe it was silk" He smiled and I said, "No, it IS linen, just a loose weave," and he nodded and headed back over to the table saying "I was right.... linen."
