Stand facing her.
Do not tell her your intentions.
Gaze deeply into the love-lights which slumber in her eyes.
These helpful tips on how to kiss a girl are part of an ad released by a chewing gum company back in 1911. It offered a helpful step-by-step guide on how to kiss a girl.
The ad for Listerated Pepsin Gum, which is making the rounds online after it was shared by Redditor muricason, offers a fascinating look at romance more than a century ago (or at least romance through the lens of advertising).
It sounds like sweet-talking your date involved a little more poetry back then, though telling a girl that "her rosebud lips remind you of cupid's bow" might get you some weird looks nowadays.
And the science of kissing seems to have changed since then, too. Above all, according to the ad, safe kissing circa 1911 required an "antiseptic gum." Seems we've been doing it wrong.
