That is until I was at work the other day and found myself getting all grumpy because no one had filled up the filtered water container for tea, again, and I had to do it, again, even though lots of us at work drink tea or some other hot beverage that we use the filtered water for. I was grudginly filling up the water container, all the while thinking, "Why doesn't anyone else ever do this? Why am I stuck with doing this all the time? It's just not fair that other people don't take their turn."
Then it hit me: all my concern about fairness was sure putting a crimp in my ability to be generous. It washed over me all of a sudden: putting such a high value on fairness was really just a cover for only doing my "fair" share and no more. And resenting others for not doing their "fair" share gives me an excuse to feel all superior and better-than-them-y. Silly Theresa. I broke out into a big grin and shook my head at myself. And proceeded to fill the water container with a much lighter heart and generous spirit.
In the days and weeks since, I've embraced my role as "water jug filler," doing my best to top up the container in the daytime and making sure it's filled in the evening so that there is water to put in the kettle first thing in the morning. And I enjoy my first cup of tea of the day much more now that it is flavored with generosity rather than resentment.
