Based on the information provided, it appears that the person you encountered was expressing her feelings about the situation and how she perceived your actions. Calling someone "strange" can be seen as a negative judgment, and her response might come across as impolite or confrontational.
However, it's essential to consider the context of the situation and the tone in which she said it. Some people may react more strongly to perceived slights or inattentiveness, while others might simply point out the oversight without using such strong language.
While her comment may have felt rude to you, it's also possible that she felt ignored or disrespected in the moment. It's always a good idea to be courteous and considerate in public spaces, even if unintentional oversights occur. If you find yourself in a similar situation in the future, a simple apology and acknowledgment of the mistake can go a long way in diffusing any potential tensions.
Remember that communication styles and cultural norms can vary between individuals and regions, so what one person perceives as rude might not be the same for someone else. In any case, it's best to strive for kindness and understanding when interacting with others.
