In my LDR we talk every night on the webcam. It is so much more fulfilling than phone calls, emails and instant messaging, all of which we do as well. I don't know what it is, but just being able to see him talking makes me feel less distant from him. It's a more definitive reminder of what it is like to be together. Plus we can send each music and pictures and surf the internet together...sending each other links, discussing things...and sometimes just sitting there for a minute and looking at each other without saying a word. 'Tis nice. I highly recommend it.
Letters would be nice, too, I might have to sit down and write one this week, SC
