Perry, i am sorry for your loss, and the further unloving nature of how you found out.
This is a truly despicable act, cowardly, and the epitome of HATE, not love.
These JW's could have, at a minimum, simply let you know via a quick phone call, or even a rushed letter thru the mail. Even an impersonal text, could have been given.
Why wouldnt they have even thought about it as a chance to "witness" to you. Maybe, the loss of your Mother could have, in their eyes, made you think about the "truth" again. But NO, the act of shunning/hating, hurting, outweighs, the act of showing love, in their warped perceptions.
It was mentioned in other posts, but we as a community, should put these actions more in the public eye. Let it be known, what their hearts are, and what unlove they show to humans.
You were wronged on many levels, the first of them being a human level, and i am so sorry that you had to go thru this.
