The Anastasia Krupnik series by Lois Lowry? In the very first one, Anastasia is in fourth grade and there's a club in her class called the i club. All the girls are in it, and the only requirement seems to be having a name or nn that ends with an i. Traci and Jenni and Cindi ... and Anastasia is mad because she doesn't see a way to make her own name end with i. Nobody suggested Staci, but that would have worked.
But anyway, it was just a fad and never came to anything much.
Before you criticize a man, walk a mile in his shoes. That way, when you criticize him, you're a mile away and you have his shoes!
