I read a report somewhere that people of my generation tend to stay in contact with our parents far more than previous generations did. I'm not sure how much of that is societal or whether it's because it's just cheaper and easier to do now wherever we are, but I'd say it definitely holds true for us here.
I try to contact my dad at least twice a week on Skype because especially since my mum died we've become really close friends. He's still obviously an authority figure when it comes to certain whatnot, but for the most part I talk to him now the same way I talk to friends. We didn't break our longest running record yesterday afternoon on Skype, but 1 hour 54 minutes is still pretty damn impressive!
