My mother-in-law swears that having children kills brain cells. “If you had only known me before I had kids,” she’ll say, “I promise you, I was really intelligent!” (I believe her too, because she worked as a medical technologist.) I feel the same way sometimes. I realize that I’m coming across as bit of a disorganized scatterbrain, and I want to say, “But I was high school valedictorian! I promise!”
