I am the middle child. When my big sis turned 16, my parents bought her a mustang. She took advantage by sneeking out several times, so they took it away from her and sold it. A year and a half later, I turned 16. I got nothing. They still had a bad taste from big sis. Ok so 8 years later, little sis turns 16. They buy her a porche 911. I was already moved out and on my own at that time, but it caused a *sigh*. I never said anything... just took note. My little sister had her own room when she was first born (as she should have). But when she was 3, my parents decided that maybe my big sister could have her own room. HELLO! What about me?? I just set back and made the choice that I had to make this happen. My big sister was a slob. My little sister had her toys strung all over as children do. I am a neat freak. So when they were out playing. I decorated "their" room. I put teen posters on one side of the room and put stuffed animals all over the other wall. They liked it, we shook on it and my parents agreed. I did everything in my life on my own. Anything I had, I earned and bought it myself. I didn't feel sorry for myself, but looking back now I see that I am stronger. Both of my sisters look up to me. The tables turn. When children are given everything, they tend to struggle later in life to fend on their own.
You have your special qualities. You ARE special. Be happy for your sister and make your own unique prosperous path. I believe in you!
