You spot a Bic Cristal stick ballpoint lying on the ground in the parking lot as you're walking in to work. Do you:
a) leave it where it is
b) pick it up and bring it inside to throw away
c) pick it up and bring it in to use--might as well
d) pick it up, bring it in, gloat mightily over having a FREE PEN(!!!) and use it all day to the exclusion of all other pens, even though you don't even really like ballpoints, and it's a skinny cheap little ballpoint at that
If the answer is d, you probably aren't right in the head...but at least it means I'm not alone.
