Two kids, one's school costs much more than the other

“If your boss gives you a company car ('98 Camry) to get back and forth to work, and gives the guy in the next cubicle a company car ('14 Porsche) to get back and forth to work - is it really all the same? Are you not going to start resenting your colleague? Hey, come on, you both got a free ride to work, what’s to complain about?”

My father had a strong upward trajectory in his salary when I was in late high school / college. Consequently, my sister, who is 8 years younger, “got” a lot of stuff I didn’t get. I drove a hand-me-down Oldsmobile Cutlass in high school. She drove a Porsche. My 16th birthday was a nice dinner and cake. Hers was an extravagant catered party. We traveled some, but she also got to take trips to other parts of the world that I didn’t get to. Honestly, I don’t remember one iota of resentment. I knew that my parents did their best for me and now they were doing their best for her. I’m fine with it. I don’t need to keep score.
