Should I reconcile with my estranged grandfather?

since you had nothing to do with this family fight and you really want get to know him I don't see why not just do it covertly to avoid drama be ready for anything though it could get nasty as he might think that you have bad motive such as spying on him or worse be honest and forthright with your grandfather explain your self to him as to why your there. He may be willing to talk to you then keep on target in your conversation with why your there be honest with your reason I know i said that be for but it's true it sounds like this will be very hard. so be prepared
