My dad died two years ago so Father's Day is a melancholy abstraction now. I don't have my own kids but I love being a godfather, an uncle, and an honorary uncle. If you're father is still with you, take him to a movie or out somewhere for culture!
My point is this: Our parents aren't with us forever. Cherish them while they are.
What's your favorite dad movie? Mine just might be Beginners (2011) though my own dad certainly would not have liked it - we were very different people. I just find it so moving in its depiction of forging new more loving relationships adult to adult with your aging parent (and others). Christopher Plummer amply earned that Oscar.
There are so many memorable dads in movies, though. Two other semi-recent paterfamilias that really affected me were Donald Sutherland in Pride & Prejudice (2005) and Brad Pitt in The Tree of Life (2011).
How about you?
