At Brazzil, there’s a good article on some differences between Brazil and the US and one of the points touched upon is PDA (public displays of affection). Here’s what the writer has to say about that…
“Likewise, public affection is the everyday norm. Although most often practiced by the young, it is not their exclusive domain. Few couples refrain from a romantic moment: witnessing the likes of rainbows in waterfalls or seaside sunrises.
One night I went to the movies at the local mall and discovered a discount promotion. My wife and I could obtain half-price tickets if we kissed in front of the ticket counter.
I learned discount kissing was a success, as it wasn’t restricted to this one mall. Perhaps movie theaters were assisting in the flowering of new relationships by encouraging the people at the back of the line to enjoy enthusiastic bursts of romance. I’m still wondering if the promotion was endorsed by the Valentine’s Day committee or the numerous chocolate stores.” – Source (more here)
