so humble, NOT

We were sitting in church my son had just got his glasses (which we had been building up). My husband was saying, "you look so good in your glasses"

Seth (3 3/4) "Yep, I am; yep I do"

Our neighbor in the seat in front of us started smirking and said in an undertone "and so humble too".
To which seth replied: "Yep, I am."
