Ever notice how when people take their shoes off other people do the same?
At the cineam yesterday, the coupe sitting next to me took their shoes off while watching the film. I took off mine and I think later one of the friends I went with took off hers.
The next day at church I removed my flip flops and left them off during the service. The friend who sat down next to me also took off her sandals.
Us human beings do have a habit of copying each other.
I believe as more people adopt the practice of removing their shoes at the door and asking visitors to take their shoes off, more people will copy them. Quite a number of people in internet discussions have commented that after they adopted a shoes-off policy, their friends did the same.
