Years ago I went on an open house caravan when I was with Coldwell Banker with one other agent in my office .  (If Dorothy Schwartz is out there, sorry we've lost touch, hope you don't mind my relating this story.)  We pulled up to one house and saw several cars and walked right in, as is the custom.   It was a center hall colonial and the dining room table had quite a nice spread of food, now this was a real lunch I thought, not just some boring tea sandwiches!  I took a quick peak at the living room and thought "this is perfect for my buyers Jim and Sue!"  I quickly said to Dorothy I am going upstairs to see the bedrooms for these buyers.  Dorothy, on the other hand, couldn't pass up the lunch so into the dining room she went to help herself.  When I stepped foot in the master bedroom, and opened the walk in closet, I heard alot of commotion downstairs, and I walked to the hallway to hear her say "This isn't an open house for brokers?" and another person saying, obviously horrified, "No!  We are having a private party"  Now here i am upstairs in their master bedroom!  So in a panic I flew down the center stairs and out the door, never stopping or running so fast!  I jumped in the car, and my colleague got in still chewing!  We never went to the real open house which was apparently right next door!  The moral of the story, start at the food so you don't miss it!
