Yes, super powers! I went to a high school where the drama department did at least one play a year in ASL. Brought in instructors from the local deaf community, and all the drama kids learned it. This was also business genius, because it basically guaranteed ticket sales. A huge number of deaf people in the area would show up for every such play, year after year. Even parents with kids at the school generally stop coming to plays after their kids graduate, but this audience was loyal on the scale of decades. It also meant that a significant chunk of the student body was now able to communicate in/across a noisy room. During assemblies and stuff, you'd see a dozen conversations in progress, not making a sound. Or, communicate near-silently. Clothes rustle and certain signs involve patting, but neither of those sticks out the way voices do. Coordinating a prank behind the teacher's back....
