Pets

when he was 6 yo, is one thing I have regretted for 80 years.
Shortly after separating from my ex, I had said something that he did not like, so he stomped his foot, looked at me and said, "You, Stupid!"
I reacted before I thought! This was something he had seen his dad do so many, many times.
It took a long time before he learned that the word stupid is is not a 'bad' word; but, to call someone "Stupid" is.

Son recently sent me an email showing a cup with 'Mother is always right' on it.
I replied with a pic of my key chain that bears the slogan, "Oh shit! I have become my mother!" Thus, it is his Grandmother who was always right.
