I got bad experience with talking on phone... never had the
habit also.
So sometimes call people and get quiet, i'm a bit scared.
Its hard to describe how i feel, but try calling your girlfriend
for 15 minutes with 9 minutes of pure silence...
That was years before of course, but now i'm still a bit hesistant
to call people, even with my renewed confidence.
Talking online is good, talking face to face is best~
