"In true dialogue, both sides are willing to change." -Thich Nhat Hanh
I realised some time ago that my father had taught me an important lesson: how to listen. That's because he rarely does, which forces everyone else to try. I didn't realise until today why I find the conversations we have so frustrating and pointless, but the above quote sums it up: generally he is fixed in his idea about things, and there is no possibility for change.
