As we walked through the crowded room Sam plugged his nose and yelled, yes yelled, "What's that smell? Why does it smell so bad in here? It stinks, Mommy. It stinks!"
In the stall I gave him a crash course in all things Marlboro. We left the bathroom and proceeded through the dining room where Sam continued to yell, "It still stinks, Mommy. It smells so bad! Where's the fire? Where's the fire?" Of course, this was all yelled whilst plugging his nose, so he had a lovely nasal tone.
Just say, "No", Sam. Just say, "No".
