Oh dear, I think I have put my foot in it. I think it must be my post which has been interpreted as ridiculing the OP. That was absolutely not my intention and I apologise wholeheartedly if that is how it read.
I was actually mocking myself, not the OP - In fact I quite agree that it a rather silly abbreviation, which is why I was mocking myself for using it. I have only fairly recently, and originally against my better judgment, started using emojis. I quite like a few of them now! If I had put a grin emoji into my post, perhaps it wouldn't have come across the wrong way. Sorry annsixty.
