Please Press the Button (2)!

Last March 16th I blogged about an idea I had: you're hurrying to an elevator and you see someone walking past it, so you call to them to press the button for you. I've never had the nerve to do that. But I did open a new vista today. I asked someone who was getting OFF an elevator to hold it for me. I'm sure I couldn't possibly do that unless I knew the other person pretty well.
