A short and amusing story for you. Last week, we had some severe lightning and thunder, and Great Grma taught Leo the word 'thunder.' He thought it was pretty cool, and called out "Thunder!" every time he heard it.
Fast forward to a few days ago. Leo was playing with his cars and trains with Grandma, and let out a big fart as he was squatting over to move a car. Grandma said "Oooh Leo, what was that?" to which Leo enthusiastically replied with a grin, "THUNDER!!!"
