Burdens of the Modern Beast
It’s the perfect posture for the Age of Insecurity. We fret about our jobs, families, country, manhood or womanhood, ability to be a good parent. We believe someone is out to get us.

After all, one must be prepared for any eventuality. Just ask any woman with a purse big enough to carry herself in.
