Austin got to warm to wear his sweater and decided to take it off. 
Question: Why did Austin do this?
put the sweater down

My son needed his diaper changed just a few hours ago. I noticed that his diaper had a distinct smell and felt full, so I carried him back to his changing table. I laid out a disposable diaper in his size and baby wipes. I took off his shorts and his dirty diaper, using it to clean up some of the mess from his bottom. I folded it over so that the outside that was clean was underneath him. I then used the wipes to clean up any mess that was leftover on his bottom. Once he was adequately clean, I grabbed a new diaper and slipped the back under his bottom. I made sure to talk to him throughout the entire process, and gave him a rattle to play with so that he was distracted. I pulled the tabs on the sides of his diaper across the front and secured them around his waist. I put his shorts back on, picked him up, and threw away the dirty diaper. He felt much better and was ready to play afterwards. 
Question: Did they throw away the old diaper?
Yes

So I stand there on the side of the street, made an eye contact with the cab driver, and raised my hand and waved at him. He gave me a quick flash of his headlights to signal that he saw me, He made his way to the side of the street. So I opened the door and got inside. I said to the driver, "let's go to the main street, Sooner the better." The driver turned on his signal to merge into the traffic. It's weird how some people yield to merging traffic, while others ignore them. I think it must be a personality thing, but it's always safer to yield. No need to drive aggressively. The driver drives at a casually fast pace, weaving in and out of lanes as needed. We got to the main street in about 10 minutes. Guess it's time to pay the man. "Thanks, driver, for getting here right quick," I said. I opened the door and got out. 
Question: Who was in the taxi?

driver and narrator
