Two friends of many years, would meet in each other's house every day. They would sit in perfect silence for a couple of hours, then the visitor would get up and leave, without a word of farewell.
The inevitable happened and, during the natural course of things, one of them died.
"You must be missing your friend a lot," said a person to the survivor, during the funeral.
"I certainly do," replied the bereaved friend. "What I particularly miss are those long conversations we used to enjoy with each other."
