Taking into account the statement above: "In Laughter: An Essay on the Meaning of the Comic, philosopher Henri Bergson writes, "Several have defined man as ‘an animal which laughs.’ They might equally as well have defined him as an animal which is laughed at; for if any other animal, or some lifeless object, produces the same effect, it is always because of some resemblance to man, or the stamp he gives it or the use he puts it to." Does "Me Talk Pretty One Day" more effectively present people as creatures who laugh or are laughed at?"
The answer is: both, because the humans laugh and they laugh at others and it depending of what we do. An example is the quote from the paragraph 4 "I realized, while laughing, that I myself did not know the alphabet. "the author laughs at himself showing him being laughed at and laugh."
Hope this helps.
