Phone Boundary Rectifier & Contact Charter

Operationalizing cell phone boundaries from Rosina Surovi Khan’s critique: silencing rings during high-stakes focus and shielding teenagers from 24/7 off-school peer torment.

“The ring from cell phones is the most annoying element when you are busy or in a critical position... You can inform your family, friends, and relatives when it would be the best time to reach you.” — R.S. Khan
