Who knew grocery shopping was so expensive?!
When you have to start paying your own rent.
You suddenly become very thankful for all those rent free years.

The horrifying realisation that grocery shopping is ridiculously expensive.
And that's just buying for one.
Not to mention how tedious doing groceries is.
The fact that your mother or father did it with whiny and demanding kids (you) makes them so much more heroic.
When you're moving house and have to build new furniture.
It was a lot easier when you could just ignore it and go play outside.
