It's really true... I've felt a little lost the last month until I got a cell phone (the one I'm still learning to use... see the previous entry on not knowing how to call people).
In some ways it's been freeing, to know that no one can try to call me. Or rather, that I can't really call anyone spontaneously.
In other ways, I do feel a little cut off. That's more related to being away from home and not making tons of new friends right away.
I haven't decided yet if I like not having a full "social calendar," and if this is more a time to recuperate, or 'lie fallow' as I like to call it. I guess I do like always seeing people and doing things.
It kind of conflicts with my perception of myself as a more quiet and introverted person, but it wouldn't be the first time I had a faulty self-image.
