Every Sunday School of my childhood ended with our Sunday School class standing in front of that little railing and reciting the Bible verse of that day's lesson. Each class would rise and recite their verse, then we'd all sing a hymn. If there was a birthday, the birthday person (young or old) would go forward and put pennies in a little white plastic church bank: one penny for each year of life. Sunday School always ended with the same prayer.
"Let the words of my mouth
And the meditations of my heart
Be acceptable in Thy sight
O Lord, My Strength and My Redeemer."
Some things just stay with you.
