As an AI language model, I don't have access to specific information about individuals unless it is common knowledge or publicly available. Therefore, I can't provide any details about Bryan and Peter's different spending habits unless you provide more context or information. However, in general, people have different spending habits based on their priorities, income levels, lifestyle choices, and personal values. Some may prioritize saving for the future, while others may prefer to spend on experiences or material possessions. It's essential to find a balance that works for each individual's financial goals and well-being.
