Hey, look kids!
Hey, look kids! A firetruck is going by!
Wow, look it’s coming right by us!
It’s turning on our street.
Hey, look, it’s stopping in front of our building…
Hey, look kids! The man across the street got stabbed!
(I didn’t actually say the last part, I just told them the nice firemen were helping a man who got hurt. I didn’t specify how.)
