LOL - I am sorry, you guys think you have it hard......... anyways... as for the earlier comments. ASL is AMERICAN sign language, language is different all over the world. Mexico have their own sign language, as well as all the countries. The reason why LSF has some similarity with ASL is because the origins of ASL is from LSF. They brought it over when they set up schools for the Deaf here in USA. If you want to learn about Deaf History you can ask me or i can recommend some great books
