I took our youngest child, our baby boy, to freshman orientation at Indiana University over the past few days.

On Saturday evening, he stayed in the hotel room with me. Sunday, we had some “classes” together on campus during the morning, then the students and parents split for different sessions, reuniting at dinner. We walked around campus for a bit after that, then he went to the student-only evening festivities, and stayed in a dorm room that evening. Yesterday we attended different sessions before meeting up around noon to head home.

The campus is gorgeous. The business school is top-notch. But the most important part of the trip was Sunday evening, when we parted ways. He wound up meeting and hanging out with a kid from Philly and a kid from Chicago. They stayed up until the wee hours of the morning. Just like the college kids do.

College is about expanding your horizons. His high school was diverse, but there were no kids from Philly or Chicago there. Soon he’ll be around 9,000 fellow freshmen from all over – East Coast, West Coast, Midwest… big cities and small towns. Over the next four years, out of that batch of 9,000, he’ll meet a handful of kids that will wind up becoming his best friends for life.

In less than a month, our baby boy will be moving into a dorm room again. Only this time it won’t be for a single evening. It’ll be for days and weeks on end.

So this entire trip was a test. A test for me. To help me practice letting go.

I passed, but barely.
