OK ! OK ?

When someone ask us for a greenlight or comment, if we agree, we will give them an 'OK' sign.



But what if i disagree ?
Sometimes i know that you want that thing so much but i really don't think that it is a good idea. How should i react and at the same time, i won't hurt your feelings? I will give you the same hand signal.
But look carefully :

All you want to see is the 1 '0' and 3 fingers up. ( OK )
But what i am trying to tell you is only the big 'O' ( zero for agreement )

By doing this, you get the answer that you want, and i get to tell you my actual feeling. So in future, don't be too excited if you get an 'OK' sign from me.( snap! snap! )
