I've had some senior moments early.

Once upon a time, two Sharyland students would skip around eight times a semester because that was the allowed amount until you lost credit. They would find ways to pass the time, Barnes & Noble, parks, and anything that seemed fun to do. Senior skip day they would hit the beach. Run away from cops, no stops. Enjoy life, not a care in the world. Every day of their lives was a "senior moment".
