How should i deal with this?

Question

my sister is the cheapest person in the world yet she is obssesed with chanel and all that duche bag ****. she cant afford none of that **** ans yet shes always showing off thinking shes better being very controlling and calling people wetbacks when she herself is mexican. Shes getting on my nerves...

Answer 1

Your sister is a poser and attempting to be a social climber. She has no sense of pride about herself or where she comes from, and probably has no self-esteem.
If she wants that stuff, she needs to get a job so she can afford it.
About all you can do is ignore her.

Answer 2

She's obviously trying to impress people in all the wrong ways. Let her hit rock bottom because after a while she will get into debt and it'll all come back to her. The only person she is hurting is herself because shes in some way self conscience so she tries to put on a front. So let her see what real life is about and let her fall because eventually she will have to get up and start being herself.
