In my defence I ask you to consider exhibits A and B below.
In exhibit A (circa 1967), my self and my sister are pictured at home on the drive. She closely inspects the workings of mother nature (a flower) while big brother looks on.

In exhibit B (circa 2009), my son and his sister are pictured at home on the drive. She closely inspects the workings of mother nature (a slug) while big brother looks on.
