I figure I was not a good shopper today. I bought the airplane ticket for mother. When I went home I realized that senior citizens have discount ID cards of 20%. And, mother gave it to me earlier as I had to buy her medicines. Whats happening to me? I am becoming so forgetful. Is this a sign of the times? I should have saved a lot of money because she has 6 sorts of medicines for her blood pressure, heart problem and diabetes.
