Really awful days at school do not last long. Have been cheered up tonight as this evenings hour of the Chelsea flower show BBC TV offering has raised my spirits. Thank you Carol Klein- you are a natural. I loved watching you, interesting , informative , opinionated, and I feel I want to know more about some Thistle called Cirsium. A natural educator, and why ----you love your subject. I am going to have a good day tommorrow, I love Escher, I am ready to tessellate , look out YR6.
