Siblings that are possibly "involved" with each other!
So my wife has this friend that she's known for about 25 years who is a nice girl but a bit odd at times, and at age 38 this girl has never been married and has never really dated and doesn't seem interested in that either. She does however live with her younger brother who's 35, and they have been "roomates" now for about 10 years after moving out of their parents house at the same time together. And they both seem verrrrry close but in an odd sort of way, and whenever she stops by to visit my wife she always goes on and on about her brother with this bright eyed look on her face. The two of them are always going out to movies, dinners, and taking vacations together to romantic spots like they were a couple. I have suggested that maybe she should start to distance herself from her friend, because the thought of incest really creeps both of us out and is totally gross!
Does this sound like these two are "involved" and if so would it creep you out as well?
