My sister & me! My best friend :)
SISTER - now there's a tip I always provide in my classes (family signs from the nose down = female; nose up = male),
the sign SISTER is a little tricky for some without seeing it. And there's variations depending on regions. One way (like in the picture) is what I called "L's to L's" Your dominant hand has the handshape of L and your nondominant hand is an L as well (just sideways).
