Why can't you step into a KH?
I feel the JW's are crazy too, but you will only hurt yourself if you do not go to your own grandmothers funeral. Isn't that what they do? If you were catholic your mother probably wouldn't step foot into a church for your funeral either. But do you really want to be like them? Be the bigger person and go to her funeral, love your grandmother as she was- a jw, and don't forget who you are- an intelligent person that sees through their lies. Just feel sorry for those that don't and sorry for their ignorance and unloving behavior. Sit in the front row- YOU are family, not them!!!
