Was at a massage centre earlier.
When I was living, one of the girl had a shock thinking that I
wore the wrong pair of slippers and walking away.
The slippers are actually one side, with one stripped and the
other another pattern, but the base and the throng strap is the
same.
A friend I remembered also wears different pattern
slippers. She and a friend each buys a pair of slippers and
exchange one piece with each other.
