It seems the words us/we are being signed differently by several different people then what i'm finding for instruction. Just curious why this is. I like the way other people are signing it (kind of like a K going back and forth) but I'm just not finding that anywhere in instructions(pointing from one side of chest and moving over to the other side)
Just slightly confusing.
That is the sign for BOTH-OF-US. Each of the two fingers represents a person. It's directional, so when the handshape moves towards the signer, that is one person, and when the handshape moves outward, that's pointing either to the other person, or the space that represents the other person.
Similar signs are THREE-OF-US with 3 handshape, palm up, circular motion, and FOUR-OF-US, 4 handshape, palm up, circular motion. The THREE and FOUR signs are moved in a circle to indicate each person included in the grouping. The BOTH-OF-US includes only two people, so that would be a back and forth motion, not circular.
So, the signer isn't signing WE at all. He's signing BOTH-OF-US. The concept is still we-two. In fact, it's more specific than "we." Saying or signing "we" doesn't tell you how many people are involved. Saying "we two" or "both of us" shows number, as does signing BOTH-OF-US.
The WE/US sign with the index finger going shoulder to shoulder is useful when there is an unknown number of people, or where the number isn't important. If it's done with a sweeping outward motion toward a group of people with the signer, then it's an inclusive "we" with all the other people.
