In the 2+ years since her brain surgery, she has apparently developed heightened senses of smell and hearing. I'm not joking. She can hear the train approaching before anyone else. She smells the coffee blocks away from the coffeeshop. She sings along with music the neighbor is playing, which is barely perceptible to the normal ear. And my other sister, M, has warned me never to fart in AL's presence, because she will smell it, and she will call you out.
The only conclusion I can draw from all this is that AL's brain is compensating for her loss of peripheral vision and slower language processing abilities in part by giving her superhero smell and hearing capabilities. Not exactly on par with flying or reading minds. But shoot, I'm impressed.
