Dear Miss Emily:

My sister moved into my house several months ago. She found a boyfriend and wants to have him sleep over some nights. I told her it makes me uncomfortable. We are both in our early 60's. She thinks i am being unreasonable. I can't be objective. What do you think?

----------------------------Miss Emily's advice------------------------

It's your home, and if it makes you feel uncomfortable, put your foot down. I have a feeling that if you allow it once, it won't just become "on an occasion", it will happen often -- and then your house is invaded by a stranger, and a man you may not even like. When you allow a precedent to be set, it's awfully hard to change it without being taken to task.  My advice is to not set the precedent in order to avoid being put in the awkward position of having to end the arrangement, once it's begun.
