Monkey see, Monkey do.
Obviously, not all things mimicked are bad. There are plenty of things that my children emulate from what they have learned, from their mother and I, that we are very proud of. There is, I will admit, plenty that they have learned from myself that I am not proud of. It is often difficult not to fall into a semi-depression when I witness and/or recall moments where my children act in a way that I do not approve, then realizing their actions were mostly due to what they themselves had witnessed in their father.
I adore the moments when my children repeat me with their little chipmunk voices. When I have hurt myself and/or am frustrated I have sometimes blurted out, "Shit!" within the presence of my children. It is a while later that I over hear my children in their play in-act some sort of catastrophe narrated with a, "Oh Shit!". It is enjoyable, at times, to hear little children use "adult" words, however, my children have been taught that there are just some words that are to be used by adults, not children, due to their lack of understanding of the proper usage there of.
Children are like mirrors, within which I often see the reflections of the good, the bad and the ugly of myself.
