A few months ago, we celebrated Sukkos. Here's a cute story from then that I found while I was going through my archives.
Ben (3) was making a sukkah decoration. He took a little strip of paper and rolled it up.
Ben: "Look - steam is coming out!"
SIL: "What do you mean?"
Ben: "Like the man standing next to the stroller. He had a paper in his mouth and steam was coming out."
The guy was smoking!*
Innocence is bliss.
* Man smoking next to a stroller. What a jerk.
