Out in the real world

I was running around the house just now when I stopped suddenly realising that I had stepped on something. I lifted my foot and discovered a slightly squashed, very dead lizard near the door at my nenek's place. It looked all dried up. It must have been dead for hours! I picked it up and brought it to the living room and began to examine it. I poked it and pulled its tail apart. I thought that was cool! At that time Nenek was cooking in the kitchen but she was curious why I was all quiet and peered behind me to see what I was doing. Nenek immediately let out a shriek when she saw what I was doing to the dead lizard. She was in a panic mode already and picked up the lizard and threw it into the rubbish bin. She made me wash my hands several times with lots of liquid soap. sheesh~ I wonder what made her freak out that much. Is it the dead lizard or just me doing an 'autopsy' on the lizard?
