I hate being the oldest. Its almost like being the oldest is a curse. I do one thing and its groundment. Little brother does something and gets "grounded" and YET he can STILL do what he was grounded from.
I think it's like a mother's instinct to, well, baby the baby. My sister was the exact same way. I don't even think her getting grounded for getting caught with alcohol at the school dance that one time lasted long. Supposed to be 2 months, I think it lasted maybe a month at most.
"He realized he was harsh. Your Dad did the same thing when he was younger, so it's unfair for her to be punished so harshly for him being a hypocrit." - my Mother.
Just think, as soon as you find a job and save lot of money, you can find your own place! Yay!
