When my grandson was five, he went with us to a church hymn singing. He sat on the front row.
I introduced the singers, and one-by-one, they came to the front of the auditorium to sing a hymn.
Toward the end of the evening, a dear, sweet, older lady arose from the back of the sanctuary and approached the platform. As she came down the aisle, she announced, "'I'm going to sing In The Garden.'"
My grandson turned his head to watch her come forward, and then turned to look at me and said in his loud voice, "Why can't she just sing in here like everyone else? Ask her to stay in here."
We all laughed. Children understand statements in a literal fashion.
If you've never heard the song, you can hear it here.
