Certain behaviour under certain circumstances we call showing our toothache other behaviour, hiding our toothache. Now would we talk about this behaviour in this way if people didn't ordinarily behave in the way they do? Suppose I & they described my behaviour without such a word as pain, would the description be incomplete? Supposing The question is: do I consider it incomplete? If so I will distinguish between two cases of my behaviour & the others will say that I use two words alternately for my behaviour & thereby they will acknowledge that I have toothache.
