Do you worship like you just don't care?

Cyan - sure, generally these are the two common ones when people stand to sing.

I'm not a teenager or a Christian but why only those two options? Can't they keep their arms crossed or their hands folded together or whatever other position?

Perhaps no espoused teenage Christians are about, but isn't that the "to whom" of where this question is addressed? Like I'm 19, and you guys are...

I can when we go to the pentacostal, evalgelical or ecumenical services.
However, I have to put my hands in my pockets at the Catholic or presbyterian service and worship with "spiritual" hands in the air!

I didn't automatically assume it was about singing. Maybe I would have asked the same though. It's clear now. :)
