The perception of a husband washing dishes in the kitchen would largely depend on the cultural and societal norms of the specific region or community the visitor comes from. In many modern and progressive societies, it is becoming increasingly common and accepted for husbands to take part in household chores, including washing dishes. In such cases, the visitor might not think much of it and may even appreciate the helpful and considerate gesture.
However, in more traditional or conservative cultures, there might still be lingering gender roles and expectations regarding household responsibilities. In these cases, the visitor's reaction could vary. Some may view it as a positive and progressive behavior, while others might find it surprising or unconventional based on their upbringing and beliefs.
It's important to note that attitudes are changing worldwide, and more people are recognizing the value of sharing household responsibilities and promoting equality in relationships. As long as the act of washing dishes is done with a positive intent and willingness to contribute to the household, it shouldn't be a cause for concern. Ultimately, visitors' perceptions will vary, but what matters most is the understanding and agreement between you and your spouse in managing household tasks.
