But my sim has also used the French Kiss to sims in French who are visitors from other countries, such as China and Egypt. Will the French Kiss be the same as the hidden trait from China; being able to greet sims like they would do it in their country?
I don't believe it's a hidden trait. When the sim is in France, they will great everyone by kissing them on the cheek, no matter where they are from - they will greet people from France, Egypt and China by kissing them on the cheek if they are in France.
Similarly, if they are in China they will greet everyone, no matter which country they originally come from, by bowing to them.
Yes, that's the greet I was talking about. What does it mean in Australia than?
Well, in Australia it generally means a more intimate kind of kissing, but I won't go into details here
