Me No Understand

This morning saw both of us off to see our doctor for our (all too frequent) check-ups.

While waiting there were two African Muslim ladies (say in their 30s) sitting to my right. Both were wearing coloured but sombre floor-length dresses/robes. The one nearer me was also wearing a loose headscarf and rather nice but sensible shoes and socks. The one further from me had a headscarf which was tight about her face. However on her feet she had nothing but a pair of flip-flips.

How can it be unseemly to display one’s head but perfectly OK to have nude feet?

Me no understand.
