LOL...jo..here is a good one about a grown man...my hubby. when we were dating he had an apartment on the 3rd floor. he never closed his blinds. he figured people couldn't see him so far up.
i was a bit early one night and boy did i get a show. LOL. i called him from my cell phone sitting in my car.

he could see me plane as day. duh..i said...if you can see me...i can see YOU!
then he turned his blinds...the wrong way and i could still see him LOL. he is not mr common sense.
i really like the course idea. might be something partment complexes would want to offer.
