Every day I have to buy bottled water to drink 1.5 liters on my room. And collect empty bottles in a large bag. When I start to feel bottles are full bag or overflowing. I will bring it to the trash tower page. Evening I accidentally saw grandmother.Her carts for trash collection bottle. I took a bag of empty bottles that hold it to grandmother. Without hesitation Also tell grandmother that I would keep the bottle again. I feel happy to see smile grandmother.
