Is Sabra an only child? Mrs. Klein doesn’t seem to be conditioned to sibling rivalry.
I’ve heard it said you’re not really a parent until you’ve had two. Because you’ve never had to deal with: “Alright, who did this?”
Look at the bright side, now she has 2 glasses of wine ready to go.
I like to say the reason I have a younger sister is our parents believed that “if at first you don’t succeed, try again.” As to why they didn’t try for a third child my sister and I figure they believed in cutting their losses.
