Airing your laundry

This is my next-door neighbours washing line, now I appreciate it could be deemed a weird or creepy thing to take a blip of, but it never fails to amuse me how her mum (she's to precious to do her own washing, Mummy comes and does it for her and hangs it out) hangs her undies on the washing line, I'd die of shame if my mum, or anyone for that matter did that to mine.... so I thought I'd share. I personally don't hang undies out for the world to see, I think it's a bit odd. what do you do with yours?
