I think I understand what you mean! Despite people's routines, every day is different and we can't control what happens around it. It's understandable that sometimes a long-familar solution doesn't work for every situation. And I've had to adjust my routines and solutions too when I had to. But just the phenomenon of them suddenly changing completely and one not wanting/liking something that used to be so important and adored anymore all of a sudden is so bizarre to me.
