Excuse Me!

I had a massage the other day.  You know how they have a 'tranquility room' that is dark and quiet with very low lights and candles?  The one I go to also has black chairs.  With all of the snow that we have, it makes it very bright outside, and when you go from that lighting to the tranquility room lighting, it is blinding and takes quite a while for your eyes to adjust.  Well, I went in and for all I could tell no one was in there, or it was full of people.  I did say out loud that I couldn't see anything, hoping someone might guide me, but no one did.  After about a minute or two, I walked gingerly over to a chair that I thought was empty and sat down.... right onto a guy's lap!  Thank God I didn't feel to see if the seat was empty first!
