That

Please allow me to apologize for what some people may see as an overtly rude gesture on my behalf. You see, ever since I have learned to communicate, albeit in a most substratal way, I feel the need to inquire as to what it is that I am seeing. What is the proper name, how it is used and why is paramount to my own communicative development. So if you see me coming your way, lacking all etiquette, pointing at an object and saying the word “that?,” please understand that I am simply caught up in a moment of educational fervor and in no way mean any disrespect.
