A common observation of many Paris newcomers is the quantity of making out. Yes, it is one in the afternoon. No, they are not drunk.
The true French kissing may not be in the style, but in the location.
Everyone seems to participate. Public displays of affection are not just restricted to the college aged. Prudeness is démodé.
And maybe that is why Paris is the city of lovers. When you are here, and in love, you are free to show it.
Because at least, as the adage goes, everyone else is doing it.
