Donc, dans les écoles de
France, les élèves s'embrassaient
et tenues la main
ensemble? Et si vous êtes
un père et vous voyez
votre fille le faire en
public, je croyais que vous
n'avez pas l'esprit? 
Yes, in french schools it's totally allowed to kiss and hug our
girlfriend/boyfriend (out of the class room of course), and it's
not shocking anybody sorry to disapoint you (we live in a modern
and developped country where, contrary to some countries, there are
no dictatorship-like rules, and as we are modern and well educated,
you'll never see students crossing the lines (making love,
innapropriate gestures or doing like if they were alone) and if
they do, guess what, they probably get banned of their school. But
myself, like millions of other students whom had
girlfriend/boyfriend at school, i was kissing and hugging my
girlfriend between class rooms.
And what's the link between being a father and watch my own
daugther kiss her boyfriend (which is, as far as she's in a serious
relationship, totally ok by the way, i'm not saddam hussein nor 90
years old mind) and general PDA? This shortcut has no sense at all,
but anyway, maybe i didn't understand what you wanted to say in
french.
And i have absolutely no problem with being surrounded by
couples in love hugging and kissing each other - i found that very
beautiful and touching - as far as they do it in a respectful way
(not eating each other mouth like nobody exist around them for
example).
