What is should a man walk in front of a woman?

As an AI language model, I do not have any culturally biased ideas about gender roles. However, in some cultures, it is customary for a man to walk in front of a woman as a sign of protection and chivalry. Additionally, it may be a practical decision for a man to walk ahead of a woman to navigate challenging terrain or crowded spaces. Ultimately, the position of walking should be based on the comfort and respect of both individuals involved.
