Love makes people do bizarre things. The acts we have come to recognize as the signposts of romance at its most fervent are nearly identical to the symptoms of mental illness: the racing thoughts, the gloriously inflated self-esteem, the nonsensical spending (compressed rock on a ring, anyone?), the promiscuity, the 'walking on air.' So it follows that the in-love would go to insane extremes to memorialize the objects of their affection. They might obsess over photographs or old letters or articles of clothing. Or, you know, make things out of their lovers' hair. On Sunday, Four Mile Historic Park hosted In the Dead of Winter: Victorian Mourning, an event dedicated to the rituals surrounding grief, most notably the morbid tradition of weaving jewelry out of human hair.
