At work once, I was at a buisness that was run out of a "converted" house setting up some computer or another.
A condom that I just happened to have in my pocket
(don't remember why) happened to fall out and on the floor.. I didn;t even notice it.
THe woman working there told me I dropped something... I was so embarrased.. the the 40 something year old woman was suddenly a lot more friendlier after that. I think she thought that I was hinting at something
