It’s a cute conversation and Sarah stayed engaged long past the stage at which I would have given up.
It starts:
SARAH: Daddy, were you in the shower?
DAD: Yes, I was in the shower.
SARAH: Why?
DAD: I was dirty. The shower gets me clean.
SARAH: Why?
It’s quite cute. Enjoy.
This is especially fitting for me today because it is my father’s birthday. While he is not and never has been a chemistry professor, we had equally long and involved conversations about all kinds of things.
