coffee and the naked soul

yesterday...i was working on a sermon in a coffee house...with these two young ladies sitting across the table from where i was...suddenly , one of them says..." i know exactly what i am doing"...i take very little notice but within five seconds i turn over one of the 30 pieces of paper i have in front of me...and it reads...and i quote..."nobody knows what they are doing "...hummmm ...i think to myself...then take another sip of my exquisite dark roast and continue on .
