Let Them Be

It's an odd way to carry on!
They're very reliable, and they invariably arrive early each day, unless it rains.
I like to sit and watch them working. Just now and then, I spot one going to a part of the garden that's already been done.
They move on quickly, but it makes me wonder why they don't send more of them together and do it all in one go - no nipping back?
I remember I'm retired and that 'hyper efficiency' is a human 'thing.'
If it's not broke why fix it? I'll let them bee. It works well enough!
