Don't snicker when someone tells you they'll pass at 8. Don't look quizzical when someone asks you to close the lights. They're asking you to turn them off. Don't neglect to buy fire insurance if you live on the Plateau. It's one of the biggest events of the summer.
Nuns enjoy it.
Don't tell someone that you think converting a church into condos is sacreligious. They might well live in one. We've heard them all before, and it causes us deep sorrow at least once a year. Usually when we find out the Quebec government is still running a deficit. Don't expect that anyone will know which bridge is which.
