Hi Cuz,
Leave myself open??  Huh?? You obviously have a better imagination than I do. 
 How did I leave myself open?

<< Oh, dear cousin, don't leave yourself open like that ;-)
 
 Among the politer replies I could think if, is, "No, I haven't, but my
 two mama cats just provided me with nine kittens. I suppose they count
 as being on this List, considering how much time they spend on the
 keyboard;-)"
