Private to Claire
Very. Relationships are problematic because even if the person says they don't care, eventually it hurts them too much to grow old while I stay the same. Others don't believe you. And once, someone I cared about accused me of being the devil because he saw me come back to life... then he killed me himself.
There hardest thing about it is that there's nothing I can do because aging is a part of life. So in the end, I'm forced to watch everyone I care about die. Some friends died in the line of duty, others just from time.
And sometimes it hurts more than anyone could imagine.
