Sorry about your dear grandfather.
Basically this jw stalked you to mark time. She probably saw you in the hospital and followed you. Don't you find this creepy? Isn't it creepy that they are trained to behave this way? Lurking around hospitals, cruising obituary columns to send tracts to the grieving and even lurking in cemeteries to 'offer' their particular brand of 'comfort'.
Their 'comfort' comes at a very high price, please do your research at jwfacts.com
I suggest anyone who would have given you a religious tract of any kind in your emotional state would have made an impact.
Please, please read the horror and painful stories of ex jw's who have endured this so called religion which is really a cult.
