The waltz is a dance of quite too loose a character, and unmarried ladies should refrain from it altogether, both in public and private; very young married ladies, however, may be allowed to waltz in private balls, if it is very seldom, and with persons of their acquaintance. It is indispensable for them to acquit themselves with dignity and modesty.
--From The Gentleman and Lady's Book of Politeness and Propriety of Deportment--
Young people these days with their wild dances. The type of things they do in public!
It's practically pornographic.
