It’s a tradition, most people do it for thanksgiving or big family gatherings.
What should you not do when talking to a deaf person?
Be careful if you have a habit of tapping your fingers or your feet as this will send the wrong message! Don’t grab or poke when you walk up behind a Deaf person. This action is commonly used as a warning that something is wrong or in an emergency. Never throw objects at a Deaf person to get his or her attention.
Hoped that helped :P
The geosphere is considered that portion of the Earth system that includes the Earth's interior, rocks and minerals, landforms and the processes that shape the Earth's surface. The Earth itself (contrary to Christopher Columbus) is not a perfect sphere.
