I suppose this would vary according to what's going in my mind. At this moment, since you mentioned "living OR dead", I'd say I'd want to have my late mother, my late paternal grandmother, and late paternal grandfather. Sad to say, but I'd leave my still living father off the guest list (this time) despite having his late parents. The three I mentioned were the most loving and pleasant people I ever had the honor to be around.

If you could re-live one of the more pleasant occasions of your life, which would it be?
