A big pitfall for many, is the need to describe every little detail around them. It can be a little insulting. My neighbor is blind, but that didn’t stop him from doing the things he loved such as skiing or golfing. One summer day, the family & I were outside playing croquet. He stepped outside, asked what we were doing & wanted to join in. We handed him a mallet & told him where to aim & how far it was. He came in third place out of 5 people. If the person has been blind for a while, they are very well attuned to the ‘new’ world. Just walk with them to make sure they avoid any hazards. If they have questions, they’ll ask & you will give the answer. It’s simple.
