One time I saw this biggest jerk.

One time I saw this biggest jerk. She was a teenager. She thought she knew every freaking thing. She made her mom miserable, caused her needless worry. She wouldn't understand until she was much older that her parents weren't too terrible after all. It took quite some time for me to see the biggest jerk. It took having kids of her own to realize that the biggest jerk in the 1980's was me.

So mom, I apologize for being the biggest jerk. 

I hope the granddaughters are enough revenge, I mean repayment. This is how I finished the sentence, I once saw the biggest.....
