My brother and sister-in-law took my father, mother, and me out to dinner and revealed that they were expecting.  Their child is due in August meaning my sister-in-law has been with child for a few months and my parents and I took to learning this differently:

Mom: I thought you had a bit of a glow about you.
Dad: I knew something was up when you said you’d stopped drinking.
Me: I noticed no changes in you that suggested that you were pregnant.
Sister-in-Law: Thank you, Terry.

One of my coworkers is preparing to have her first child in early April and as the delivery date approaches she’s scheduled lab testing such that tests involving loud startling noises occur far from when her baby’s due.  She was not amused by my attempt to schedule random double-blind starter pistol testing for late March.
