What do these idioms mean? ..Post by Archana S Kumar, XI B

1. Once in a blue moon
   Something that happens very rarely
   Eg :I see him only once in a blue moon.


2. Blow one's own trumpet
   To boast about one's own achievement
   Eg: without meaning to blow my own trumpet, I came top of the 
         class.
3. Play it by ear
    Rather than sticking to a defined plan you will see how things go
    and decide on a course of action as you go along
   Eg: Let's see how the weather looks and play it by ear
