Chives could not possibly fathom that he had to perform CPR to a rotten corpse. Chives got so confused that he left the corpse behind and started to promenade to his house. When he had reached his house he was famished. Since he was famished he went to the supermarket nearby and had bought a chicken to cook and eat. When he'd finished the chicken he began to realise he became parched so he walked to a lemonade and asked the man who was standing there and said " I know that you sell lemonade but do you have grape juice?" The lemonade man gave him grape juice but it looked peculiar, the colour was velvet red but Chives didn't care so he drank it and had a really grand old day.
