Why are x's kisses?

The phrase "x's kisses" typically refers to the use of "X" to symbolize a kiss in written communication, particularly in letters or messages. This tradition likely originated from the practice of signing documents with an "X," which was often accompanied by a kiss as a gesture of sincerity and affection. Over time, "XOXO" has become a popular way to express love and friendship, with "X" representing kisses and "O" representing hugs.
