My roommate is my best friend, but she habitually puts on way too much perfume on herself. I have to open the window once she leaves. on her way out, i smell it when she walks by, a number of feet away from me and it lingers in the room. I have to even open a wondow for a few minutes. I have tried explaining to her nicely that she puts on too much, and that it is more noticeable to others than her, because one is 'immune' to her own perfume, etc. I acknowldge i am sensitive to scents, but this is really riduculous and she does put on too much. I also know from other experiences, she doe snot have a very sensitive scense of smell which can contribute to the issue. short of having her perfume mysteriously 'disappear'-not very friendly, what do i do? it has got to stop.
