“Sarah Imenu went inside and did not wish to interact with or even be seen by the guests.”
Yet Avraham Avinu did not refrain from leaving his door open for guests.
So, are we to conclude that since we are not avram avinu we should abandon hachnosas orchim? Or perhaps, we should tell our wives to lock themselves in the kitchen for the duration of time the male guests are in the house? Or, perhaps we are to conclude that we should arrange for separate seating when having company?
