i thought his blindness would be a handicap for him... boy was i wrong, its a case of the blind leading the not so blind for him, the only thing he has issues with is low density objects like bushes, chairs and human legs, ive seen him, in a complete strangers house, cut to one side before he ran in to a wall and parallel it as if he could see it... i am beginning to believe its some form of echo-location, like, he can hear his footfalls bouncing off of them or something, it is very bizarre and incredible to see first hand.
