I'm not giving it the justice that Rick Lee would, but...
...Sitting out in the sunshine today this butterfly landed on my shoe after flying around me several times in uneven circles. It crawled all over my shoe, up my leg and onto my shirt, apparently confusing me for a big red and white flower.
I just sat there sunning myself and smiling, watching it flutter about on trembly, spindly legs as its wings capsized this way and that in the breeze, as a billowing sail.
It was a nice moment.
