In fact, our relationships are more important to us than any anything else.
Example Evidence for this, if we need it, can be found in such things as the last messages sent or spoken by those who knew they were about to die in the 9/11 plane crashes. The final messages were all expressions of love towards those they had meaningful relationships with. No-one left a last message to make sure their car was serviced regularly or about maintaining the service contract on the central heating boiler.
