Mexico has it's own sign language, that we are learning now.
There are some similarities. The alphabet is pretty much the same. But there are glaring differences too.
For example, once I was trying to converse with a deaf woman of Mexico when she asked me in what I thought was ASL
"You, lesbian?" to which I was shocked and confused.
NO! I signed.
She looked at me again and signed "You, America?"
Uh, yes . . . And I asked her to spell out what - to me - was the sign for lesbian.
She spelled out i.n.g.l.e.s. (that's Spanish for "English")
The ASL sign for lesbian is the MSL sign for English.
Yeah, just in case anyone asks you where your from.
