Despite my premature elevation to grandparent status yesterday (see below) two things today told me that this was premature.
First, the youngest S Clark (*who someone thought was my granddaughter yesterday*) was so so rude to me this morning that I realised she must be my 16 year old daughter, as no one could/should be that rude to their grandfather.
Second, same S Clark left her shoes in the car and I had to go back and drop them off! This time I heard the lady I gave the shoes to say "S C's father has just dropped her shoes off!!". Yeah!!!!!
