Please choose the correct ending to complete the given sentence: Education and Communications: [header] How to help a blind person [title] Greet the person out loud. [step] When you walk into a room where a blind person is waiting, saying something right away will alert them to your presence. Being quiet until you're right next to the person might make them feel as though you just snuck up out of nowhere, which isn't comfortable for anyone.

Ending1: The person may be very annoyed, so express that to them by introducing yourself. [substeps] Say something like, " hello, i'm _ _ _ _ _ _. Ending2: [substeps] Try not to sound excited when you start saying " hey, what's up? " because it distracts the person, causing them to turn and look at you. It also may make the person feel more comfortable that you're looking. Ending3: [substeps] Say your name so they know who you are. If the person offers a hand to shake, go ahead. Ending4: A simple " hi " with a smile is enough to break their grasp on the situation. [substeps] If it's more comfortable for you to speak to the person yourself, it works just as well.
