The email arrived like a gift, a slightly shocking, beautifully wrapped present. Amelia, already humming a jaunty tune, read the words, and let out a small, breathless laugh. She twirled around in her creaky desk chair. This was, as the kids say, *chef’s kiss*.

Her fingers itched, not for a pen, but for... well, everything. She visualized the university's mascot, a rather grumpy badger, wearing a party hat. She grabbed a highlighter, and began defacing the syllabus with silly drawings. This, she thought, was the dawn of a new era.

A small tremor ran through her, not of fear, but of… something else. Adventure? Yes, absolutely. Adventure.
