Human: What is the difference between a teddy bear and a bear? Assistant: 
The main difference between a teddy bear and a bear is that teddy bears are usually smaller, softer, and more cuddly than regular bears. They also tend to be made of materials like plush fabric, plastic, or stuffed with cotton. Regular bears, on the other hand, are typically larger, harder, and less cuddly than teddy bears. They are often made from denser materials such as fur, rubber, or wood.
