As a new public service here at charleysblog, I’ll occasionally point out things that happen which reinforce the truth to me that, yes – I am working at a Chrisian School.
How You Can Tell etc. #1:
You’re showing a DVD in class in which a large orchestra and a conductor are demonstrating the various instruments of the orchestra, in a very serious, Caucasian manner. (Hey, it’s the Dallas Symphony Orchestra). They come to the 
“percussion” section. A man is seriously demonstrating various percussion instruments, one of which is the tambourine. As he very seriously and emphatically strikes the tambourine in an orchestral kind of way, a girl shouts out:
“Whooooo, we have those at our church!!!”
(“Church,” in this case, being pronounced “charch.”)

Wait a minute…was this girl who shouted out happened to be named Tracey Partridge??!! XO
When they want your attention, do they say “Hey, Mr. Tambourine Man?”
