Danifoxpt and Cecilia RN,
At the risk of sounding like a smart alec, I might respond to the " how much have you lost this week " question by saying, "I'll tell you, if you tell me". That might shut em up!
As for the secretary who wants to know about riding your bike to work...a rather to the point reply would be, " why do you care about my transportatio? Are you looking to buy a bike and that's why you want to know about mine?" Or even better..."would you like to start meeting me for a bike ride? We could ride to work together! It would help with thoseounds you've gained recently"'. That should shut her up, and fast. A little bitchy I know, but it seems to me that most people just say what they think without one thought to everybody else. You might give it a try.
