He happened to be my father There are two children in our family.

I have a sister four years older than I am who is exactly like Mother, and she and Mother were inseparable.

I am exactly like Father; because we understood each other, and because both of us always new, although we never mentioned it; that Mother preferred my sister Eileen to me, Father tried to make it up to me, so from the time I can remember I was at his heels.

It never bothered him to have me playing around in the library while he was writing his most complicated treatise.

I have waited in his car half a day at a time, playing or reading, while he watched a patient or delivered a lecture at some medical college.
