Dear diary,
I was walking home from school one day and decided to take a different route to school,little did i know,i walked right into a couple of boys throwing rocks at a poor puppy.Its was a horrible sight,the puppy was whimpering,I felt so bad for that poor puppy so i told those mean boys to stop before i call the police on them for animal cruelty.The boys ran off,scared to be caught,I knelt down to make sure the dog was ok.Lucky he was still breathing.A rush of relieve went through my body,I called the animal hospital and they picked him up instantly,i rode with him to the hospital and they said he had a couple cuts from the stones and then they patched him up and said "We'll look after him till he's better"I said "ok" .I walked home and thought what would've happened if i didn't stop them?...
