"English does oblige you to specify certain types of information that can be left to the context in other languages." A researcher at the University of Manchester explains how language affects thought: "If I want to tell you in English about a dinner with my neighbor, I may not have to mention the neighbor’s sex, but I do have to tell you something about the timing of the event: I have to decide whether we dined, have been dining, are dining, will be dining and so on. Chinese, on the other hand, does not oblige its speakers to specify the exact time of the action in this way, because the same verb form can be used for past, present or future actions. Again, this does not mean that the Chinese are unable to understand the concept of time. But it does mean they are not obliged to think about timing whenever they describe an action."
