Yummy, Happy

Poirot speaking to Ariadne Oliver in Third Girl:

One day you rang me up. I was in distress. Yes, I admit it, I was in distress. Something extremely painful had been said to me. You, madame were kindness itself. You cheered me, you encouraged me. You gave me a delicious tasse de chocolat.

Never underestimate the cheering power of a cup of cocoa.
