God is like the dentist… He wants to fix everything.
Let me explain. When I was a child I often had toothache, and I knew that if I went to my mother she would give me something which would deaden the pain for that night and let me get to sleep. But I did not go to my mother-at least, not till the pain became very bad. And the reason I did not go was this. I did not doubt she would give me the aspirin; but I knew she would also do something else. I knew she would take me to the dentist next morning. I could not get what I wanted out of her without getting something more, which I did not want. I wanted immediate relief from pain: but I could not get it without having my teeth set permanently right. And I knew those dentists; I knew they started fiddling about with all sorts of other teeth which had not yet begun to ache. They would not let sleeping dogs lie; if you gave them an inch they took a mile.
