2023 - What's made you Happy today?

The day before yesterday I found loads of Black fly on the young growth of a young Rhubarb plant. We had visitors and I was too busy to blast them off with the hose, which is what I usually do. Yesterday I counted at least 10 Ladybirds on the plant. This morning I looked again and the plant was virtually clear. Just goes to show that nature really will take care of itself if life alone.??
