When you indicate the number 3 with your hand, which fingers do you hold up?
Thumb, index, middle fingers?
Middle, ring, pinky (small finger) fingers?
Index, middle, ring fingers?
I heard Germans do it one of these ways, English does it another, and Americans does it yet another way. Don't know if it's true, but I think I saw that in some movie. Maybe Inglourious Basterds by Quentin Tarantino?
I swap between 1) index, middle, and ring and 2) thumb, index, and middle because I was raised with 1) but learned to do 2) while learning American Sign Language, as 1) in ASL means the letter W.
