ANNA AND LANA WERE UTTERLY EXHAUSTED AFTER THEIR LONG DAY WORKING ON THE PROJECT. AS THEY SAT TOGETHER, REVIEWING THEIR NOTES AND DISCUSSING NEXT STEPS, FATIGUE BEGAN TO TAKE ITS TOLL. THE ROOM FILLED WITH THE QUIET SOUND OF STIFLED YAWNS. FIRST, LANA COULDN'T RESIST THE URGE, LETTING OUT A BIG YAWN THAT SEEMED TO ECHO IN THE ROOM. ANNA, CATCHING SIGHT OF LANA'S YAWN, COULDN'T HELP BUT YAWN HERSELF. IT WAS A CHAIN REACTION — YAWNS BOUNCING BACK AND FORTH BETWEEN THEM, ALMOST LIKE A SILENT CONVERSATION. SOON ENOUGH, THEIR TIREDNESS BECAME PALPABLE, BUT THEY COULDN'T HELP BUT CHUCKLE AT HOW CONTAGIOUS YAWNING TRULY WAS.
