I went into the nearby corner shop today to buy a few groceries. While I was in there, a woman entered the shop who was wearing fluffy bedroom slippers.
I can never understand why people go outside in their indoor slippers. Not only does it defeat the object by getting them dirty, but also carpet slippers are not very strong and they wear out really quickly when you wear them outside.
Does it really take that much effort to switch from slippers to a pair of flip flops before going outside?
