The dumbiest thing i did was breaking my ipod. When i was five years old, I had an ipod. One day my ipod fell from me by accedant and the cover opend. After few day's, I wanted to open the cover to change it, so I threw the ipod from my bed on the floor very hard, then it broke and became like powder. At the beginning my parents were angry, after they knew the reason, they began to laugh.
