No good deed goes unpunished, eh? It was nice of you to help her but no need to subject yourself to abuse. She may eventually out that you were right. Needless to say, you deserve an apology.

Stop helping her then. Once it clicks that's you're right, she'll shut up and do as you say.

So what your sister is saying, is that she's unemployed and you're doing Sarah Jessica Parker, a famous actress with money? Neat.

Well OP after that you could go the route of Screw her if she's gonna be rude I'm not gonna help or go the hey you're a [insert job your sister wants here] can you look at her resume and tell her why she might not be getting a job route me I be the first one no one likes getting rude comments

It's better off she doesn't get a job, because that way no one has to deal with her.

My sister is the same, if you try to help her in anyway she'll be a bitch about it

Well..her loss...

Tell her you'll shut up when she can spell 'clueless horse-******' flawlessly.

She just doesn't want a job, she passes out resumes because she wants your parents to think she wants a job that's all it is.

FYL…unless you really HAVE been ******* horses; in which case, YDI.
