Don't even know why I tried fucking liking my sister in law again!! I started working where she works (at a nursing home) almost a month ago and I love my job. Then a couple of days ago she went running to my husband telling him that "I might be getting fired" because apparently someone said I "can't do anything right" even though I've gotten compliments already and the manager told me the only thing I need to work on is my speed (I'm a housekeeper) . And then my husband told me that most of the time she lies. Then I tried asking her about it and she lied to me saying she didn't know what I was talking about and denied it. Wowww 😂😂
