My church small group was meeting last night at somebody's house. The hosts are always shoeless, but they don't ask people to take off their shoes.
A guy who had not been before came in with his shoes on, but he took them off when he saw that those who had so far arrived had removed theirs.
A few of us had removed sandals or flip flops and were in bare feet. In the past I often found that many people removed shoes in winter when visiting homes and wore socks, but people seldom removed sandals to go barefoot in summer. These days I am finding that people do remove their sandals and go barefoot when visiting homes in the summer. I think this is one of the biggest indicators I have seen that habits are changing.
