I was at home today. I cooked the dinner and when my sister came I asked her to wait until the parents come. She refused. I watched her angry face to look at me because of proposing doing something for others instead of just satisfying physiological needs. I watched her silently and said to myself that I should refrain from reproaching her. it is so sad when someone thinks so much about oneself instead of listening to ones conscience .it is so much better to overcome my basic needs in order to do something nice, eg. eat together.
