A friend from across the pond adds at the end of posts, "Tra." I assumed this was one of those expressions like "Ta ta." It expanded to "Traaa." It now seems to have escalated to "TRAAAAAAAAA." Is this random, or a stuck key, or maybe something I am supposed to know or understand?
In our family "LOL" was added to messages to mean "lots of love" so I am still getting used to "laughing out loud."
