Well it's understandable if you're in denial. Obviously you weren't attached in a literal sense, but how could you have survived without them unless you changed the lifestyle you lived in college? That fits the definition of an umbilical pretty well. You already said you had everything paid for and just had to work a bit for your beer money, which probably isn't even 100% true.
To echo one of your statements, the kids who would never admit they were attached to their parents by an umbilical cord, tend to be the ones who have everything paid for. You need to at least give a fair analysis of the situation when you want to make one sided statements. If you honestly think that living on your own in a college dorm with all expenses paid isn't an umbilical cord, not in a literal sense, then you and I just see things different.
Again...there's nothing wrong with having everything paid for, but how can you sit here and say just because you're living own you're own that you basically aren't still attached to your parents (without them you would starve or not be able to function, which signifies the umbilical cord) and depend on them? Ok maybe calling it an umbilical cord is a bit derogatory, but what would you call it then?
I plan on helping my kids with college. That doesn't change the fact that if I'm paying for everything they will still be basically attached to my wife and I by an umbilical cord. If they don't follow the rules and perform, then it'll be severed.
Since you like to keep saying I'm sorry you parents couldn't help you. I'm sorry you're bitter you really know that you were still attached by an umbilical throughout college. Get over it....college was the easiest four years of your life and you know it..
