About a week after I graduated from college, I broke the news to my father: I was leaving the family plan. He had been paying my cell phone bill for the previous five years, after giving me my first phone at 17. Before cell phones were standard for teenagers, my father would make me empty my pockets before I went out with friends to show him I had a few quarters for a pay phone—just in case. But as soon as my first boyfriend started hanging around our house, he handed down his old phone without me even asking. Daddy’s little girl was expected to check in on the regular.
