Standing in the garden centre, looking at the dripping roses, trying to get an idea of their fragrance on a warm summer day I am aware that the lady nearby is humming. Humming in public places irritates me. Especially when I am trying to think. I look at her and see that she has dressed up to come to the garden centre on this wet day, pearls are much in evidence. "Isn't it absolutely glorious!" she says, waving her arms to embrace the aisle of David Austin's finest creations. I cannot see past the sogginess but I want to make this lady happy and so I tell her that I went to Mottisfont when the roses were at their peak. "Ah...how fortunate you are...you will always have that...when times are bad you can remember the roses at Mottisfont in June" she says and smiles at me. I watch her walk away, humming, and wonder at the kindness of strangers.
