Monday evening: my throat hurt a little, 16 year-old's throat hurt a little.
Tuesday evening: my throat hurt a lot, 16 year old's throat hurt a lot.
Wednesday morning: I have head and chest congestion, 16 year old has head and chest congestion.
Thursday evening: 20 year old mentions his throat hurts a little. I lay out the roadmap, "Tomorrow it will hurt a lot, Saturday will come congestion."
Saturday morning: 20 year old comes to me, "I know you told me the course this would go but I really thought I wouldn't get congested - I thought I would be special."
Got to love youthful optimism.
