    This page certainly has all of the information I wanted concerning this subject and didn’t know who to ask.


    Three humble shoemakers brainstorming will make a great statesman.


    I’m amazed, I must say. Rarely do I encounter a blog that’s equally educative and interesting, and let me tell you, you have hit the nail on the head. The problem is an issue that not enough folks are speaking intelligently about. I am very happy I stumbled across this during my search for something regarding this.


    Under a tattered cloak you will generally find a good drinker.


    One flower will not make a garland.


    Deep doubts deep wisdom small doubts little wisdom.


    False friends are worst than bitter enemies.


    Death always comes too early or too late.


    I know by my own pot how the others boil.
