Dear Queenie,
My mother-in-law has a key to our house in case of emergencies. I suspect she uses it when we are not at home, because little things go missing, like food and cleaning supplies and sometimes even tools, dishes and cooking utensils
I don’t want to cause a family fight, but this has to stop!
Queenie, what do you suggest?—Invaded
Dear Invaded,
Change your locks! Do it at once and without telling your mother-in-law.
If she asks you why you have done so, ask her how she knows. Then, without accusing her of being the culprit, tell her what you have told me about things going missing. You will know from her reaction whether she indeed is the guilty party and whether you can trust her with a new key.
