So I've learned a few movements here that are offensive to the people, but not necessarily offensive to Americans, and we do them all the time.
When calling a child, especially, we turn our palms up point to the individual with our pointer finger and pull it in and out calling them to come to us. This is very offensive to the people.
When you are calling someone you are supposed to put your palm down and use all of your fingers to call someone by pulling them in and out.
I just learned today that to a Tibetan (and I only know this because he was Tibetan and no Nepali's around to tell me if it's offensive to them as well) it is rude to point with you pinkie finger. You are supposed to use your index finger.
Most of the Nepali people don't use their hands to point at all though, they use their lips.
I don't really understand the whole "Let me take a picture of myself making a kissy face."
Now, I realize they are just pointing at the camera! It make sense now. They've picked up on the Nepali custom!!
