" Once bitten, twice shy." If a dog bites me, I shall be twice as careful in future when I see it. This proverb is also used to apply to many things and not only to dogs. For example, if you have been cheated at a shop, you will not go to the same shop again. "A bird in the hand is worth two in the bush." If I am a hunter, trying to catch birds, it is better to catch one than to see two birds in a bush but not able to catch them. Thus this means that what you have already got is better than the chance of being able to get something bigger in future. " Don't be a dog in a manger " means " Don't be selfish." In a stable ,the manger is the place where the horse's food is put. Sometimes a dog will sleep in the manger and bark when a horse comes to get its food. The dog doesn't want to eat the horse's food in the manger but it will not let the horse eat it. " He who pays the piper calls the tune ." A piper is a musician. The man who pays a musician can say what tunes the man will play. Thus this means that if a man provides the money for a plan, he can say how it will be carried out. "To pour oil on troubled waters" is to try to calm things down. Oil is lighter than water. If a ship is in trouble at sea, another ship may come to help it.
