To get someone’s attention, Deaf people might tap someone on the shoulder. Or, they might bang or tap on a table so that the vibrations cause everyone at the table to look toward the source of the vibrations. In a large group or classroom setting, flashing the lights off and on is a common way to get everyone’s attention. It’s rude to wave your hands right in front of a Deaf person’s face to get their attention. Just gently tap them on the shoulder instead. It’s ok to wave your hand, though, if you’re too far away for a shoulder tap. Here are some commons mistakes hearing people make when trying to get a Deaf person's attention. These are generally considered inappropriate or even rude.
- stomping furiously on the floor
- turning the lights on and off when you're trying to get just one person's attention, and not the entire group
- aggressively jabbing the person you want to talk to
- waving your hand right in front of the person's face
- grabbing the person's hands to force him or her to stop signing and pay attention to you (never, ever grab a Deaf person's hands--that's like someone putting their hand over the mouth of a hearing person)
