crimson not slovenly! No it is a self-rewarding day, we deserve it as often as we feel like it. Think of all we have done for others over the years, now its time to reward ourselves.
I always wash etc but then just do what I feel like each day but never put make-up on unless I go out and then not much.
I think I have 'do what I like days' which is pretty much every day for me as we gave up trying to please others when we retired and now please ourselves, be it gardening, housework, excercise, doing things for the family/others etc. Retirement is great
