As a public service,
My Two Innings hereby presents a highly reliable differential indicator of masculinity:
1. Holding purse momentarily for wife/girlfriend/female relative: Chivalrous. Masculinity retained, provided purse is not held by the strap.
2. Walking more than one step with purse: Traveling Violation. Masculinity not retained.
3. Important Exception: Retrieving forgotten purse from mid-priced family restaurant on a Sunday is permitted, provided the bag is grabbed in the same way that Brett Favre holds a football while scrambling -- confidently yet haphazardly, with arm extended downward at full length for maximum distance between the purse and bearer's line of sight -- and is in no event carried by the strap. Bearer must glance around furtively and return to the vehicle at a hasty trot.
Recap: Holding bag, okay; walking with bag, not okay. Thus informed, you may now proceed with confidence.
