When there is not enough time to say what we need to, do we just stop talking?
or
When everyone is silent is it because people are thinking?

If true friendship is when silence between people is comfortable, then it means that silence would make most people uncomfortable, which would imply that perhaps thinking makes people uncomfortable. then can friendship only exist when we are comfortable with each others' thoughts? So, even if we have a lot to say and a lot to think about, it seems like the most uncomfortable place to be is in the middle of silenced thoughts- between friends.

How do we determine the lengths we go to achieve a goal in exchnge for the lengths we would not have to go if we gave up the goal?
How do we know when roads are intersecting and when one is simply yeilding to the other at its end? (and at an intersection, who has the right of way?)
