I slouch in my seat in Calculus, gazing absentmindedly at the abstract streaks of dry-erase that mean so much to the roomful of students around me and think about how badly I want to get out of my favorite place in the world.

"The first year is the hardest," they all told me. My cousin Colleen, class of 1999. The Howard Hall Frosh-O staff. My parents. My advisers. They all said the same thing — that once I made it through my freshman year at Notre Dame, the last three years would seem easy in comparison. I spent all of first semester waiting for the hard part.

Orientation and the first few weeks were a blur of stir-fry and SYRs, late night bonding and early-morning lake runs. Classes were easy, football season was in full swing and college was fun. Even as the golden autumn turned into gray November, I still loved every minute. I wondered when the hard part would arrive.

December was, looking back, the last month of innocence. We dressed up in miniskirts and neon for the Dillon '80s dance and frosted cookies that disappeared within 20 minutes of being set in the third-floor hallway. We had wine and a "tailgate bagel" on study days, people-watched in CoMo while avoiding cramming for finals and felt invincible when we did well anyway. My Texas and Tennessee roommates greeted the first snowy morning with awe. We exchanged teary hugs as they flew south and I drove north for vacation.

Maybe I romanticized it too much over break, proudly showing my state-school friends pictures of the Howard Hoedown and rushing the field at the Michigan game. Maybe I raised my own expectations as I gushed to my relatives, sounding like a brochure without trying. I returned to campus on top of the world.

Reality hit. At the end of January, I received a minor in a tavern ticket. Two months later, I owed my parents more money than I could be proud of, struggled to complete my community service hours, and wondered when I became a person who got into trouble. I realized that it took more than reading about life outside the Notre Dame bubble to understand it, and I realized, as I painted dilapidated kitchens and cleaned dog kennels, that perspective is the hardest thing to gain.

Each minute of math class drags on toward the end of the day, and each day drags on toward next Wednesday. We will finish packing and close the door of the quint that has hosted so many disastrous parties, emotional outbursts and deep conversations relieved with both hilarious and heartfelt advice. I'm ready to close the door on my freshman year. But next semester, I'll be excitedly — and realistically — ready to come back.
