I'm lucky to have some friends that I do. One of my good friends from DC emailed me to arrange a phone call, out of the blue. I haven't had a real conversation with him in months.
On the phone he told me that as an introvert, it's really hard for him to call people. It's uncomfortable. Extroverts often have the same discomfort. But my friend has decided to address it head on - just because we don't live in the same part of the country doesn't mean we shouldn't be close friends. That will not be my last phone call with him, and I am proud to call him my friend.
