I noticed that too.
I haven’t see a nun wearing a habit in YEARS, likely decades, it’s been so long.
It’s a shame really, because tha Habit automatically evokes respect.
We have a Nun-Rich environment here in So Cal/ Pasadena & Alhambra areas. There are a cloistered convent, a retreat house, a monastery where nuns live and give workshops/ teach, and a Mother Teresa’s “R&R’ home where women come in from the field to rest. Across town there are a couple of retirement homes they run as well. We see them, ALL in full habits, walking around, in our church which is run by Discalced Carmelite friars.
Some of these groups were founded by Irish priests coming into this ‘mission field;’ some of the groups of nuns came up from Mexico during the persecution in 1920s.
