Is AUTHOR wrong in the post ? POST : My husband’s sister (we’ll call her Mandy) is a bitch. She orders everyone around like they’re her own personal servants (even her own mother who enables it), and she’s ALWAYS yelling, talking over people, and trying to control every situation. Simple things like how the family kids open their Christmas presents, how we order at restaurants, and how we play family games, how we stand for photos, etc., have to be controlled by her. I’ve given up fighting this for now because I can’t stand being around her let alone talk to her about something sensitive. 

She’s also an anti-vax, stay-at-home mom who thinks that essential oils cure diseases. She is constantly bugging me to get in on her (pyramid scheme) products she sells on Facebook. She comes to my house to tell me that I will poison my future children with my cleaning wipes. I’m POSITIVE that my husband’s mom pays for a good portion of her living expenses as well (which would be fine if she had a real job and tried to improve herself). Basically, she is the textbook example of everything I loathe in a human being. 

So...

Her daughter is in kindergarten. I have seen her assignments first hand. I’ve also heard her read. She is functioning on grade level, and does not appear to struggle in school. 

Mandy just texted me to ask if I will tutor her daughter one day per week because she is “struggling to sound out words” and gives her a hard time when she tries to practice with her. 

I know Mandy doesn’t plan to pay me because sh’s a bitch and has no extra money. 

I am a licensed teacher (k-5) with SO much on my plate. I really don’t want to give up a portion of the little free time I do have to tutor a child (for free) who is functioning on grade level. 

I haven’t replied yet. I feel guilty for saying “no” because I like to help people out. I’m just so stressed in my day-to-day life. I’m also a professional educator who doesn’t want to work for free to tutor a child who doesn’t need it. If she did need it, that would be a different story. 

AITA for thinking of refusing this?
