Using pet names or endearments is only permitted between lovers and family members. Doing so otherwise is a blatant insult. Sending items like accessories, dresses, or shoes (or handkerchiefs and watches for men) to someone indicates romantic interest. If a young lord appends 'Lady' or 'Mademoiselle' after requesting something from a young lady, it is practically a confession. If he adds a complimentary adjective (such as beautiful, radiant, or jewel-like) before 'Lady' or 'Mademoiselle', it is essentially a public confession.

Stepping on a partner's foot on purpose while dancing is a sign in high society that means, 'I dislike you.'

A knight kneeling and kissing the back of a lady's hand signifies an oath: "My everything to you."
A nobleman kissing a noblewoman's hand with one hand behind his back is a polite, casual greeting. However, kissing her hand without placing his hand behind his back is an act of courtship.

A nobleman gently holding a lock of a noblewoman's hair and smelling its scent signifies that he is attracted to her and is asking where she is going.

A noblewoman or young lady intentionally letting her fan or handkerchief slip and drop while passing a nobleman indicates her interest in him. If the nobleman picks up the dropped fan or handkerchief and returns it, it is an act of acceptance, showing he reciprocates her feelings.
