My Mom: "My paycheck was late again this week, Uncle Rob's cousin has inoperable brain cancer, the oil change for my car was $120, gas prices are going up again, and I think I'm developing a rash - which I hope isn't that superbug Staph infection going around..."
My friend, later that day: "How's your mom?"
Me: "She started to aganoise, so I had to ignore her."
Friend: “Meh. She’s such an agony ant.”
