Hold it in front of her so she can see it then eat it right there. You got her something nice and helped her with her diet. Such a good child!

Again proving the old adage, no good deed goes unpunished.

Either you genuinely don’t do nice things for her or she’s crazy. Whichever it is, spending a dollar on her after she complains won’t fix it.

Also, buying something after the fact really isn’t nice. You’re just trying to cover your own ass.

it probably just confirmed even more for her that you don't care or listen to her :/ it's probably not about you, and even if it is you should talk to her and see what's bothering her.. she's your mom

Your mom sounds like a lovely person.
