When I was 9, Uncle Jerry came and picked me up from the airport and we drove my by the Gateway Arch. He's talking to me and asks, "You wanna go to the top of that? I'll take you." And I said, (without knowing you actually CAN go to the top) "We can't get up there!" Then a couple years later I found out that you can go to the top and Aunt Melissa and Kelly took me and I totally regreted not saying yes to his offer at the time.
Most of the time that Syndey and I were watching tv, Uncle Jerry would be asleep on the couch. And everytime we tried to talk to him, he would reply with giving us measurements. I remember laughing really hard and we just started saying all these measurements back to him!
