Mom: "What does it mean that I dreamed that I got a 70 in Algebra?"
Me: "Is that a dream or a memory?"
Mom: "Oh no I did fail Algebra in HS but I asked our Principal, a nun, to pass me because I had high grades in other subjects and she let me."
Me: "Wow what a faulty education system we have. That dream is your guilty conscience speaking after so long."

Mom: "Oh yeah because I saw an offer for tutoring Algebra on Facebook yesterday. That must be it."

Mother indeed knows best
