Girls, Hey girls, especially British or American ones. Why do you get so wild on vacation , even if you are engaged or with a BF?

I live along a lovely coast with many touristic towns, and I've noticed that most girls, especially from the UK or the USA, when on vacation.. they only care about drinking as hell, laughing as much as donkeys and... well riding as many guys as they can ! Why pretending to be so calm and with your so called " British self - control" in your home country... but then... when you leave it... most of you turn out to be just so slutty?
