Classy and brassy

Today, I stood alone outside our church whilst a big wedding was going on inside and a large group of kids, hoods up, walked slowly towards me. I fought the urge to back up when one called over "hey, lady, God bless you".
So I smiled and said thanks and they sauntered off chatting when the same one sang something - his mates boxed him because he was singing.
He shoved them back and said - "leave off, it's a song about Jesus".
That's classy and brassy.
