Leena,
You must be on your way to Korea and I hope you will have a safe flight and a wonderful time over there with your husband.
Please take the following words in good spirit;
I would like you to talk with Benyapa when you are back. Indeed you known being a women is not very pleasant when it comes to share a bathroom with a man who isn't either her boyfriend, husband or brother and I am aware that she has been affected last week when your husband were at the Target home.
I think that if you share a lunch only You and Benyapa on your return, you could tell her that you know she feels disturbed by your husband presence in the home but that you are saving money so this is why you can't take a hotel room and nicely ask her to accept is presence and that you will make sure that your husband will be very discreet (just imagine if it was you who were alone). I am sure Benyapa in this case will understand and if you are nice with her she will understand that your husband stays with you.
You are a clever girl, I trust you, you work nicely and I appreciate you very much so I am confident you will understand the above and be nice with Benyapa (she deverses everyone to support her).
I am sure that all will be fine and that you will stay with us for many years.I want Target Officers to be as family.
We will refurbish the five Target Factory rooms so everyone will have its own bathroom and toilet and a lot of privacy :-)
I am looking forward for you to be back. WE MISS YOU and thank you for your understanding
Once again have a wonderful stay and all the best and you can count on my support
