Now a famous remark that French philosopher Denis Diderot included in a letter to a young female friend presumably on the verge of womanhood.  These words haunt me, perhaps because in my experience they ring so horribly true.  I am currently living somewhere in the middle of my own adolescence and that of my children's.  By the time my kids are teenagers, I would like to have made peace with the fact that I used to be one.  Right now?  I can't.
