jilio, what do you mean "False"? To which part?
I've heard SEE is decreasing on various anti-SEE or pro-ASL only websites. Am I wrong that it's decreasing?
I don't have any problem with people using SEE, but I wouldn't learn it as it's a lot more work to have sign English and to have to sign every single word when they aren't needed, and ASL is far more popular, so if any other sign language I'd learn ASL (I'm a native Briton so I study BSL). I like dropping things which aren't needed during the conversation, as well as having two signs for "happy" and "merry" when one is enough.
However, a few signs are always useful to know, which is why I was curious as to a couple of them.

It does seem like it could be a lot harder to sign sentences in, though maybe it's because I'm used to dropping "to" and "ing" and stuff.
