Just a scenerio. What will happen if one day you desire to eat a piece of cake that your friend has, and its the only piece of cake that's left such that in doing so you will deprive her of enjoying it? Will you still tell her the truth so that you'll get to enjoy the cake very much? Your friend may have generously offer you the cake in the end, and you're glad for getting it but somehow there's still the feeling of guilt knowing that you may have done a selfish act. Haiz, you can nver have your cake and eat it.. and I've just experienced such a dilemma. Still feeling bad..
