I planted these things one year and now have a yard full - they are everywhere.
We saw written on a T-Shirt the other day:
It was a great opportunity to see neighbors that we haven't run into over the winter months and to meet the new neighbors who moved in across the street two weeks ago. My husband met her husband the day after they moved in when her husband was trying, single handedly and unsuccessfully, to haul a washing machine up their front steps. I was watching his attempts from my front window and poked my head out to ask my husband, who was pruning trees, to go over and help. "It's the neighbourly thing to do" I said. His look was a dirty one as the last time I said that it turned into a four hour job and he was not a happy man.
Helping someone is just the right thing to do.
