Joseph, my point is exactly that. Hosts and their spouses, whichever genders they may each be, should feel comfortable vwith their guests of the opposite gender.
As a seminary student I ate with my fellow students in many types of homes, many Litvish and even modern homes, and we mostly spoke only to the female members of the household. It’s only in the US and in certain frum communities where theres the breakdown of formality between the genders and “everyone is friends”. I’m not saying you can’t talk to your guests if that what’s done in your community, but there still must be reserve when interacting with the opposite gender and many people have lost that reserve.
