when say that because fsl and gsl and and asl appear the same so they must be similar and be like say because you can speak french and german and or english it be all similar and a you know isn not the case . believe it or not and they be very much different and there be no such thing a universal sign . although there be a few sign that be similar and just like we say no and in spanish the word for our no be in fact and no . but really and a deaf person who sign asl would have a very hard time communicate with someone who sign gsl . sorry to be give you an educational piece and but you write it so i have to comment it and i do not want you to look bad to the deaf community . thanks and have a great day .
