I feel like ASL should be taught to more of like everyone, I see circumstances where it seems like it would be useful frequently (either quiet or really loud places, like libraries or where there is heavy machinery, or from driver to driver in cars where you can’t hear them)

also not sure of all the SLs that exist and what attempts have been made towards standardication. I imagine there is more than just American SL / ASL for SLs but I haven’t looked in to all the ones that exist
