space and time

After a long time, today, I spoke to my call center friend, who works at night. I was wondering how I hadn't spoken to him in a long time in Bangalore but here i was speaking to him. This is not a note to whine but just the concept of space and time applied to personel.
Now, what was not possible because of time even when spatially possible is now possible because of time while space is not even a constraint. Well, thanks to western economy, time difference and telecommunications.
