Ok. I am going to put them on the washing line. I don't want to insult the hoors or anything. But I suspect they cater for fetishists - and I'm pretty sure one of their customers likes to steal things off washing lines.
The scenario -
1) Hoor goes out to put out her washing to dry. Hoor gets holiday gift. All happy.
2) Other neighbour goes out to put out their washing to dry. Finds present. Thinks it belongs to the Hoors. Much hilarity ensues. All happy.
3) Underwear-stealing punter goes out to steal underwear. Steals thong. Punter happy (and presumeably hoor also as she knows someone is impressed with her standards and has thus labelled her "professional")
I'll have to wait a few weeks to do it because I can't get into the drying green at the moment. Mysterious, eh? ;)
