The seed of a blue lupin will usually produce a blue lupin. But the seed of a blue-eyed man may produce a brown-eyed bore...especially if his wife has a taste for gigolos.
It was not till I experimented with seeds plucked straight from a growing plant that I had my first success...the first thrill of creation...the first taste of blood. This, surely, must be akin to the pride of paternity...indeed, many soured bachelor...
I think it is silly to be amateur about anything when one has an opportunity of learning.
