If you could chat with anyone, dead or alive for one hour, who would it be?

I think my grandmother. She died before I was born and I wouldn't personally have anything to say to her, but my mom has unfinished feelings with her and misses her so much that if I could talk to her mom and come back with a message or note from her mom she would really appreciate it. I think it would give her peace and rest a little easier about their last year's together.
