When I was about 5 I found my mother's book "What to Expect When You're Expecting" and I was fascinated by everything in it. Something got lost in translation, however, because I thought a trimester was a doctor's appointment you had to go to three times when you were pregnant. Well, my neighbor was pregnant, and one day my mother asked if I'd seen her, and I said, "No...maybe she had to go to her trimester today." That gave her a good laugh.
