Interpreting whether someone's behavior is rude can be subjective and dependent on various factors, including cultural norms and individual perspectives. However, based on the statement you provided, your neighbor's response could be considered direct and straightforward rather than explicitly rude.
Your neighbor may have had reasons for her response, such as concerns about her own dryer being overused or the possibility of inconvenience. It's important to consider that the tone of the conversation, non-verbal cues, and the overall relationship with your neighbor could influence your interpretation of the situation.
It's worth noting that the most accurate assessment of your neighbor's intent and attitude would come from a direct conversation with her. Open communication can help clarify any misunderstandings and maintain a harmonious relationship with your neighbor.
