Just say what you feel and think
A difficult one, hm... I guess I would keep my cat (an infinite source of fun), my home, my bed, my cooker and a recipe book. And I will starve to death because I didn't keep any food xD
My truck, my two PC's , my old 30-30 Winchester, my swimming pool, and my airplane ! Those are my favorite things. Possessions that is. LOL
