It does seem silly. Sundays are a good time to invite folks to your home for dinner, and any good guest knows that a bottle of table wine is a welcome host/ess gift.
Of course, if you are careful not to offend, or you are dining with Baptists, you may opt for flowers or loaves of French bread. ;o)
FRENCH BREAD!! How offensive! Only long loaves of crusty AMERICAN bread at our house! /s
Are you kidding? Baptists love coming over to my house. It's the ONLY chance they get to drink!
