How to walk with a blind person

Actually, it's very simple. Offer him/her your elbow. Two fingers on your elbow are all that is necessary for a blind individual to follow your lead. He/she will walk slightly behind you. If you begin climbing steps, a signal will be sent, because your elbow will raise up. Conversely, when you descend the stairs, your elbow will move down. Also, any turns that you make are signaled in the same way.
