Sometimes the hardest conversation to start is with the person who means the most to me. When I am in the grocery line, I can carry on mindless small talk conversations with total strangers. But when it feels like the stakes are high, I can invest lots of emotional energy in thinking about building the relationship, but my additional efforts seem to lead to a microscopic result.
In our relationship, my dad was not exactly a phone call talker. He spent lots of time on the phone for his job. So, I guess I can understand why having long heart-to-heart conversations over the phone were difficult for him. I think our average phone call lasted a mere 60 seconds.
