Gabe's funny

Gabe is a smart boy and always likes to learn what new words mean. He is always asking me the meaning of words he has heard and then he always tries to use his new words in his every day conversations. So the other day we were going somewhere in the car and it was sunny outside, so Gabe and Avery both had to wear their sunglasses (having the sun shine out here is a rare occasion). So while we were driving Gabe and Avery were talking back and forth when Gabe all of a sudden got quite annoyed. "Mom, Avery thinks he's porky with his sunglasses on", Gabe said.
"What? Who's porky" I asked.
"You know mom you taught me that word".
"What are you talking about Gabe, I don't know what you mean".
"You know when someone thinks they are so cool, they are porky".
"Oh Gabe do you mean cocky?"
"Oh ya, Avery always thinks he is so cocky when he wears his sunglasses".
He usually gets the words right but this time he was a little confused. Once Gabe realized that the word was cocky and not porky he then asked what porky meant. I said that sometimes it can mean that you are chubby. Avery thought that was so funny and told Gabe that he was the porky one. Gabe didn't think it was too funny but Avery sure did. We sure had a fun car ride that day.
