Human relations and hazard

Let's face it- the more people are physically apart the more a real relationship needs some kind of planning and organization.
You run into the people next door all the time. You can decide to have a drink together or spend time together on a whim.
The same exists with virtual relationships: what a pleasure to meet a friend on messenger and to start a ramdom chat for a few minutes or longer, keeping you from work, but that is what human relationships are about...
Things get complicated when you want to make virtual and real ends meet- For suddenly real life limits become important: the time spent on transport, other obligations, work to do, ...
suddenly relationships become choices in between alternatives: see the close-by friends or travel to see the far-away. Choices can't be made anymore on a whim, encounters at that level aren't subject to accident anymore.
Those small continuous choices become a big choice of life- stay on local level for real life and leave the virtual level in the dreamsphere? or broaden the view and look out for the new in risking to loose spontaneity?
