I'd like to have a housewarming but I have one friend who is quite outspoken. She will speak her mind and sometimes says things that upset people. She can be tactless. I know people may ask why im friends with her but otherwise she is a good friend, she can be very kind. However I am worried about her offending someone at the party, especially one member of my family particularly who is very sensitive. Not inviting her isn't an option, she is part of a large group of friends and it would effectively end our friendship. How would you handle this one? Would it be unreasonable to have a bit of a word with her beforehand and say my relative is sensitive or something?
