yes or no

What do you answer for a 'yes or no' question? you can either answer 'yes' or 'no' or 'don't know'. But how do you decide on the answer? You may say that it depends on the question and your knowledge on it. No matter how much you know about the question or how much you investigate to answer the question, there is 50-50 chance of getting it correct or wrong when you reply 'yes' or 'no'. Hence just answer 'yes' or 'no' whichever you like and sometimes 'don't know'. Definite questions like "Are you in Seoul?" are some exceptions.

Moreover, even if you get into the 50 % chance of getting the correct answer, then there is only 50-50 chance of getting marks (or getting recognized) for your answer. Because, many times wrong answers are appreciated. Hence why at all do you have to think? Just answer 'yes' or 'no' whichever you like and sometimes 'don't know' :)

Furthermore, if you are going to get another chance for your wrong answer, you can try 'yes' first and then 'no' or vice versa. Example, whenever my laptop windows gives a big message with yes and no buttons, I will just click either of them without reading. If at all I had chosen wrong option, I may choose the other one when windows asks me again.

One other thing about yes or no - Usually people shake their head 'up down' for yes and 'right left' for no. But most of the Indians shake their head 'right left' for both yes and no :) There will be some difference in the way so that other Indian could identify if it is yes or no. But other people could not differentiate this causing lot of confusion. Moreover most of the Indians shake their head as they talk.
