I love #3. This texting shorthand from grown ups is totally annoying. It's ok when my 15 year old does it - and amazingly she doesn't do it with me. But from grown ups? DId we not learn to spell already? Ugh...such a pet peeve.
You did so good here. Yes, you have no requirement to answer abusive text messages. I love the way he set you up on this one. So childish...and you saw the game for what it is and refused to play. Way to go, WTBH! Well played on your part.
