Has anyone come up with their own hand signals? I dive with my sister, my brother in law and my boyfriend, and we have come up with some hand signals of our own!
My sister's favorite is to point at some creature, then put her hands out to the side and shrug her shoulders - it means she wants me to tell her what it is (on my dorky wrist slate).
We've also come up with signals for "take a picture" - you just hold up an imaginary camera, then point to the thingy you want them to take a picture of.
If we see something we think is kinda freaky we will point to the freaky object then make "biting" motions with our hands.
I am also guilty of coming up with my own sign for "my goodie bag is too heavy - will you carry it for me?".
Pathetic, eh?
