Like plumbers crack, sometimes people have no idea whats visible at any time. You lucked out it being cleavage.
Ive had a few welcome cleavage shots from pretty ladies, and a few unwelcome incidents. One particular incident i had to endure a 25 minute interview with a guy who was pitched back in his chair, was wearing shorts and no underwear apparently, and his balls were fully visible from my seat.
Wanting to make a good impression on the guy, i couldnt bring myself to embarass him by pointing out his indescretion, so went through the whole interview, the 4 of us. Him, me, and lefty and righty.
