Feeling guilty

I may have killed my greenhouse plants. I've been away for a long weekend and didn't arrange for anybody to water the greenhouse. I didn't even set up the watering system before I left or water particularly thoroughly as I had a tired, tearful, three year old in the car and I had to drive to Scotland. I didn't even go today as I had a tired, tearful, three year old in the car. Tomorrow will probably be too late. All that nurturing gone to waste (well, apart from the several kilos of tomatoes, cucumbers and chilli peppers I've harvested).
