3. Doesn't try to read or take my help
4. Short tempered with my sister (age3)
5. Has an attitude 90% of the time
6. Got her iPhone stolen. YES I SAID I PHONE WHY DOES SHE HAVE ONE I don't know?
7. Doesn't carry book bag to school. Goes empty handed.

9. Lies compulsively about everything

But she got a tablet! Brand new. I'm more than upset. I'm trying not to be upset about it but wtf man I'm doing great right now and what do I have? I just get yelled at. Now I'm going to work to earn money so I can have nice things which angers me bc I'm struggling between sleep school and work. Tell me why a person who can't read gets a tablet? Oh! She's not down syndrome or anything she's in special ed due to laziness which put her behi

Jealousy is when you count someone else's blessings instead of your own. It sounds to me like you are very jealous and that is all about you.

Maybe she's just a spoilt brat. Don't let yourself get upset over that; it's all just materialistic. If your can work hard then you will get the things that you work hard for - and trust me, when you get something because you worked for it, it feels so much better and right than just getting it from someone without really trying to do something for yourself. Ignore this feeling of being upset and just move on with your life. I understand why you're upset and it's not entirely wrong but you honestly shouldn't be since I'm sure you have better things to do.

I learned many years ago that life isn't always "fair". It continues to amaze me that poor behavior is sometimes rewarded, instead of good behavior… Sounds like you've got a good work ethic too, by starting work at your age.
Hang in there! It sounds like you have more common sense & better values. You'll come out ahead, in the long run.

Many adults have pity and compassion for the slow and behind especially if they are female. To reward them is the only way to show sympathy for their condition or to say secretly " I'm sorry for the way you are but I don't know how to help you.' Don't be angry about this, males are always thought of as self reliant and can manage on their own and it is expected so.

Ask yourself would you want to change places with her and receive the things she is rewarded with or would you rather hold your own. If you saw two men without shoes and one can work and get a pair but the other can't - who would you give an extra pair of your shoes to first. Know when you are blessed and others are not - it is one of the steps to manhood.

Omg trust me, I've been in SAME situation, my lil sis (15yo, I'm 16yo) is really bad at studying and she always fails, on the other hand, I always get A scores and everything. And they always treat her better than me if she succeeded in a one subject, my parents would make a celebration for her, and If got a B score they would scold me and ground me. I talked with them about it, and they understood, and I've never felt that way ever again, maybe you should talk to your parents?
