Channel 7 reports:
Broadway is in South Boston.
Anon dummy was telling this other dummy to live in Dorchester. Obviously those people who live in Dorchester wouldn't possibly be able to fall into the tracks at Broadway, because...
... just because.
Despite the introduction from the anchorguy, who got it right, the reporter signed off by saying she was reporting live in Dorchester.
If you're going to call someone else a dummy, it would probably help your point, if indeed you have one, to spell Dorchester like you can read and write.
