A new missionary recruit went to Venezuela for the first time. He was struggling with the language and didn't understand a whole lot of what was going on. Intending to visit one of the local churches, he got lost, but eventually got back on track and found the place. Having arrived late, the church was already packed. The only pew left was the one on the front row.
So as not to make a fool of himself, he decided to pick someone out of the crowd to imitate. He chose to follow the man sitting next to him on the front pew. As they sang, the man clapped his hands, so the missionary recruit clapped too. When the man stood up to pray, the missionary recruit stood up too. When the man sat down, he sat down.
When the man held the cup and bread for the Lord's Supper, he held the cup and bread. During the preaching, the recruit didn't understand a thing. He just sat there and tried to look just like that man in the front pew. Then he perceived that the preacher was giving announcements. People clapped, so he looked to see if the man was clapping. He was, and so the recruit clapped too.
