My wife and I flew SFO/CLE earlier in the week. We were in coach (E+) on UA. There was a mother and baby across the aisle and a row forward. Mom brought her baby and car seat (window), and she sat in the middle as to not disturb the aisle passenger. When we landed, everyone stood up. That's when I figured out the man in the aisle seat next to her wasn't her husband. As I'm pondering this fact, I saw her get a backpack. I realized that she'd never be able to manage the baby, the car seat, and the backpack. Everyone is standing around watching this go down. I said to my wife Ask her if she needs help. She thanked my wife and said that would be wonderful. I took the car seat and my wife took the backpack. She told us her husband was meeting her at the gate. That's my good deed. What about yours?
