Raising your grandchildren because your children are too busy having fun
Constantly bailing out your children
Your children living at home
Co-signing student loans at the age of 68
Oh, and death when you cut their allowance.
I cannot emphasize enough that you rich people keep spoiling your children. They're royal cunts to deal with when we have to grow up, date, and tolerate them in our generation. But the results are hilarious when they come back home at 34.
