A nose lid?

Anyone familiar with Andrew knows that he gags (and throws up) very easily. Lately, strong bad smells have caused him to start gagging.

The other day, we left the house for school and Andrew said that it was stinky outside. Apparently the stinky followed us into the car because Andrew asked me for a "nose lid."

"What do you want, Andrew?"
"Mommy, I need a nose lid."
"Why do you need a nose lid?"
"To protect me from the stinky," he said as if this was obvious.
"What?"
"Mommy!" Andrew said exasperatedly, "I need a nose lid to protect me from the stinky smell!"
"Oh, ok. Well, we don't have a nose lid."
"Ooohh. We can go to the nose store to buy a nose lid."
"The nose store?"
"Yeah, the nose store. That's where you buy a nose lid."
"Oh, well... I don't know where the nose store is."
"That's ok, mommy. I tell how to get there. First, you go on the turny bridge (the North on-ramp) vroom, vroom, vroom and then drive next to railroad tracks for a long time and then turn corners and you are there."
"Really? Those are good directions. Maybe we should just get you a new nose."
"No! mommy, you're being silly. I can't get a new nose. I need a nose lid to protect me from the stinky smells."

We decided we would talk about it again after school. Luckily, he forgot about it by the time I picked him up.
