David Einhorn, whose hedge fund Greenlight Capital has a large stake in Apple, took to the airwaves yesterday and touted a plan in which the iPhone maker would issue preferred shares as a means of returning cash to investors and boosting the share price: "Steve is not with us anymore, and that is negative in many ways, but it is positive because Apple doesn't have to be committed to that way of thinking at this point in time."

Well, now we can add one more duty to Ms. Sandberg's list of adult responsibilities: managing Zuck's philanthropic giving. According to Fast Company, emails released last month show that Ms. Sandberg played a major role coordinating Mr. Zuckerberg's $100 million donation to the support Newark, N.J.'s public school system.

In the emails, the planning team talks candidly about trying to make the donation look participatory, getting big names and big round numbers involved, and making sure the billionaires look "modest" and feel "special."

The emails, which can be read in their entirety here, speak to the degree to which Ms. Sandberg took control of managing the process of completing Mr. Zuckerberg's generous donation. In an email to Newark mayor Cory Booker and one of Mr. Booker's advisers, Ms. Sandberg asked for a breakdown on operating expenses for the fundraising, and details on community outreach efforts. In another email, a Facebook communications employee says he reworked a press release announcing the gift at Ms. Sandberg's encouragement.

Talk about micro-managing! Some things, it seems, are best left to the grownups.
