Yup, it's good you have learned this. When my boys were mid teens, they at times bemoaned the fact that the kid across the street bragged about his car to my boys. They told me and I said that they had a lot more to be proud of because their cars were their's because they had earned every penny for it + every ounce of gas and all the insurance had been purchased with their money. The boy across the street hadn't worked a minute to earn his car. It was handed to him on a platter. And you know what he didn't appreciate it.
I'm not saying we shouldn't ever have parents help us with stuff because mine certainly have helped me over the years. But the difference is that this kid bragged about his car and technically it wasn't his to brag about.
