The words

Mom:  Here is a math test from Harvard..

Older brother (David): take a look and give an answer

Younger brother (Tom):  take a look and give another answer

mom:  Tom has the right answer

Younger brother (very proud):  I beat you, David.  I beat the Berkeley graduate..

Youngest sister (Betty, 6 years old): Looking at Tom screaming..
(Tom wasn't sure what's going on.)

Mom:  Betty doesn't like the word, "beat".  You probably change the word.
   
Younger brother:  ok.  How about I use this word, "I win".

(Betty seems to feel better)

---------------

A lot of times, different people have different logic and words.
As long as everyone tries to understand the meaning of each other and change the words that both people can agree upon.
Then, the world (family) is a happier place.

Asking

Younger brother (Tom):
we went to "Toy R Us" to buy video game for nintendo switch.  We got it for 10 dollars

Older brother (David): That's great..

Older brother: Mario Kart or Pokemon

Younger brother: mm.. Why do you expect Mom to buy the expensive sixty dollars video games.

Older brother:  mm.. (not sure what Tom is talking about)

Younger brother:  (puzzling, not sure what David is talking about)
               
Mom:  (looking at both brothers smiling)
   
      Tom and I went to "Toy R Us" and bought a 10 dollars video game.
      It's an old video game called "skylander".
   
      I think  both of you misundertood each other.

      When Tom says that he bought 10 dollars nintendo video game, David expects it to be the most popular nintendo video game.
   
      so David thought that we have Mario Kart or Pokemon video game now.

      Now Tom got confused.  Tom is thinking that Mom doesn't usually buy expensive stuff.
      Why does David think Mom is willing to buy the most popular video game.

The lesson:  A lot of times, it's better to ask people to explain than to assume.
                    It's better to understand than misunderstood.
