Joey, one of the main characters in the television show Friends, is famously known for his love for food. However, there are some things that Joey doesn't share. He is possessive of his food and often becomes defensive when someone tries to take a piece of his pizza or sandwich. In addition, he doesn't share his feelings easily and keeps his emotions bottled up. This often leads to misunderstandings in his relationships, as his friends don't always know what he's thinking or feeling.
