Noisy Spaces, Quiet Faces

I've noticed whilst wearing my HA's, that my ears take a bit of time adjusting to noisy places. I can hear people directly in front of me much clearer than before, along with all the extraneous washes of noise. I've also become more self-aware of just how much lipreading/face-watching I've been doing over the years without realising it! This is yet another reason I want to relearn sign, so that I can talk and clarify something if I miss it, you know? But, seeing how I studied in Middle School and again in University, and forgot almost all, save the alphabet and a few signs, I really want to take it up again!
