100 words is all you need

How many words do you need to communicate with other people?  And what would your list of 100 include?  The article here gives the 100 most commonly used words in the English language but, of course, that doesn't mean they are the ones you need most.  I would have thought there ought to be a fair sprinkling of nouns - for that would have to include "tea" coffee" "computer" "phone" "car" or "bus".  There would have to be "sea" "rain" "cold" "sun" and something to do with money like "pound" (or "dollar" or "Euro") and "card".  States of mind: ""miserable" "happy" "sad" or could I do those with mime?  And I would need some numbers, too.  In fact, if I could mime one to ten with my fingers, I would still need enough of those, say twenty and so on to make up the list.  And then there are those things you need to be able to understand on the phone when trying to get through to the call centre "press" "key" "hash" and "star" and probably "Could I speak to your supervisor?"  What about shopping "Have you got this in a larger size?" and "will you give me a discount because these are weeks past their sell-by date?"  There' that's my 100 already.  But wait a minute, can I find room for "friends" "Facebook" and Blog"
