Greeting card from past or future?

The first thing to do with anything like this....is rule out the non paranormal, usually that's where the answer is...is there a possibility that the ex has your handwriting down ad is trying to annoy/bother/upset you? Or any of the possibilities brought up above. Too often people want to jump right to something paranormal and those of us that are experienced in the paranormal, know that most of the time, it's found to be non-paranormal...rule out that first, then look to other possibilities, never underestimate and ex either.
Now I need to get out of this forum as I have been in it far too much lately and you all know how I hate that!
