So having these connections is essential, you would say...
To lack is to be unfortunate?
Can we truly lack such things? We are shaped by our experiences. Those who we have lived with, spent time with, or perhaps even cared about have given us the form we wear. Even if they are not physically present, one could take comfort in being who they are because of that person... that person an inexplicable part of their makeup. The shake of a hand, an embrace, or a ruthless punch all weave into the fabric of the individual.

We cannot lack when we carry such things around with us.
