for a long time when emerson would pray with us... he really liked the amen part. whenever we got to amen he'd clap and cheer. now he's begun saying amen as if it is an ending to any exciting thing he's doing... so for example... when he plays his drums... he completely wails on them and then looks up and shouts "AMEN!" or when he sings a song, at the end he shouts "AMEN!". or say someone opens a present and is excited when they see what it is... well that's occasion for an amen too. maybe he's a pentacostal.
