Baths.
Long, hot, candlelit baths with fig bubble bath from L’Occitane.
With only my nostrils breaking the surface of the water, I can lay submerged for up to an hour in meditative bliss.
Or, sometimes, I just read.
That said, having the luxury of time with two young uns about is pretty rare. The silence usually broken by, “Daddy, I need the loo!”
