They are not necessarily the days when magic happens — these days of magic. They can be quite ordinary and may deserve no more attention from us than what the other days deserve. It may be a weekend day, when part of it is spent at work, a small bit reading and a short nap. And then you would go and have a lovely dinner at a new place.
I like these magical days that, otherwise are not magical at all. While not being magical themselves, they bring out the magic within us. And that smile you have, which you just cannot stop using.
Such magical days, perhaps have a lesson for us: every day can be full of magic — if you are willing to believe.
