Would you let a relative or friend do your taxes? Why or why not?

No, my youngest sister offered several times. She has an accounting degree. Told her my taxes were simple enough that I could do them by myself. I would have paid a stranger before letting her do them if they weren’t simple. She would blab out how much other people were making as if it was her right to do so. She also offered to help me set up a budget. I didn’t want her in my business at all and I am very good at paying my bills on time and being frugal with my money when necessary. She’s also a narcissist so there’s that.
