I watched a robin take a long bath in this shallow dish of water this morning. As well as bathing in it, birds drink from it, the swallows need it to make mud for their nests, it brings the sky down into the garden and reflects things in it. You can also tell at a glance if it's raining. It's an important addition to any garden however small. (I am scarifying the grass - it always looks worse before it looks better!)
When I am trying to make a decision I still find What would be simplest? my favourite helpful question but here is a good one from Gretchen Rubin -
What is the value of what I'm going to get if I...........?
