As a child, my mother explained why I should never do prank phone calls:

"What if the person you're calling is some old lady sitting near her phone, and the sound of the ringer startles her so badly that she has a heart attack and dies? How will you feel then? Pretty guilty, I bet. It's just not worth the risk!"

When accounting for the source of my neuroses, I offer the previous as Exhibit A.

April favorites.
