Eating has always been associated with friendship.

"To eat salt" with an Arab forms a most binding contract.

Even "the serpent" in the book of Genesis commenced his acquaintance with Eve by suggesting a meal.
It almost seems as if there were certain unwritten laws in American society, assigning certain functions to certain days in the week.

I do not believe Americans are superstitious, but I found that Thursday was greatly in favor.

I remember on one occasion that Mrs.Grant, widow of the late President, sent an invitation to my wife and myself to dine at her house some Thursday evening; this was three weeks in advance, and we readily accepted her invitation.
