Gratitude Monday -- No Real Reason Edition

Gratitude is a wonderful thing. It can sneak up on a person and, for no obvious reason, this person feels grateful.
Such happened to me yesterday. I had a great day. There is no one reason for it. It simply was. I had a wonderful sense of well being and am grateful for it. Yet, it is not the reason for my gratitude.
It was a contributing factor, but not the cause.
I like to understand things. I like to reason out the reason for something in order to understand it.
As near as I can figure it yesterday was a gift from gratitude: "Here, have some just because. There's plenty in the bank."
Fine by me.
And I am grateful for it.
