This is lovely.
I have tried this in the past, when I thought someone might need a boost ~ that includes people I've had problems with, if I thought they needed it. I wish I could maintain a good attitude with the latter, one-hundred-percent of the time, but I suppose some is better than none (I'm working on easing any defensiveness I feel - it isn't usually an issue, but is there in certain situations. Even then, if I know something is
really wrong, then the bad feelings disappear ~ I get that from my parents).
(*edited out personal situation.)
This also reminded me of a part of the book
Eat, Pray, Love that reminded me of The Intention Experiment (I quoted it
here), that was an example of this type of thing (sending love) really seeming to help someone.

I have to add that the thought of people doing this, out in the world, really perked me up this morning.

I especially love that your daughter is sending love to all of the children in her class.
