My blokes mate just came round and my knickers were in middle of kitchen floor! I had dropped them whilst taking the washing to the machine. He never said a thing though but they were right there infront of him and I knew he had seen them and he knew I knew he'd seen them. Picked them up as soon as he was out of sight.
There was a knock at the door at mine one day when I was single. Turned out it was a friend of my parents they had met on a cruise. I invited them in and made a pot of tea adn as we sat there chatting I realised the ALL my underwear was hanging over chairs - I was mortified. Funnily enough, they never called again.
I went around to a lady's house to look at the satellite system. I sat in lounge with cup of tea, looked across to chat .. and there were a pair of her knickers hanging out of the cushion divides.
Never said anything on that particular occasion : )
I remember some years ago a gas guy came to check our gas fire in our rented property, he moved the sofa to find the rudest porn magazine hiding underneath ermmmmm......
The boyfriend buys them very rarely just the wind me up and puts them places I will find them when cleaning, I told him this but I don't think he believed me.
I took a box out of our brothers room once ( it contained a keyboard) and took it to school. When I pulled the keyboard out, all his porn mags fell out too!
I think knickers are very likely to be hanging around all sorts of places at the worst times, Because I find the delicate ones don't like to be over dried in the tumble dryer, so they are 100% air dried or at least part air dried to finish them off, so I often hang them on door knobs I mean handles lol.
