Just a little one shot that I wrote, set during the end of Season 3. I don't usually write a lot on Willow, but the first line of this popped into my head and after writing it down the whole story just flowed.
Read and enjoy!

I never believed in magic, not really. I guess I was a lot more open minded than some, looking back, but that was just me. Seeing was believing in my eyes, or, even better, a theorem was believing. Give me some substitution and a constant pattern and I'm putty in your capable hands. That was me.

Thinking back, I probably would have stayed like that. If I'd never met her. Sometimes I wonder what it would have been like if she hadn't been called. Would she still have come to Sunnydale? No, I guess she wouldn't have. She would have never been expelled. She would have been another asinine beauty. That's what she tells me, anyway. Except for the beauty part, that's just a given.

You're telling me.

Xander! This is my rumination. Go away!

Wil, use your people words. Not all of us are human dictionaries. Besides, I'm simply agreeing that Buffy is, in fact, a hottie.

Don't use her name! I was avoiding her name for effect!

Whose name? Buffys'?

Xander!

Oh, right. Sorry. Okay; Mrs. H is a complete hottie. H for Harris. Except, Buffy – the future Mrs. Harris. Not my mother. Hands up if you're not going to sleep tonight.

Shouldn't you be doing your trig?

Shouldn't you?

I'm finished.

Good. You can do mine.

If I do will you leave my thoughts alone?

Only in the literal sense.

Fine. Give me the sheet.

Thank you! I love you Willow!

Yeah, yeah.

Anyway, I was good in school, I would have topped the year every year. I would have helped Xander, and he would have passed. Say that night never happened - the night we lost Jesse; Jesse, Xander and I would have passed through our high school lives, never being there. Not like we are now.

As strange as it sounds, I like knowing what goes bump in the night. I like being able to help, even if no-one knows it. I think if I hadn't met her, I would have been a mathematician, or maybe a scientist. Maybe I would have decided to work for those computer guys and the government. I certainly wouldn't be heading to Sunnydale College next year, but I'm okay with that. I'm glad, even.

I don't think I'd be the same person, if I hadn't met her. She taught me a lot. Carpe Diem.

Fish of the day?

No Buffy. Live for the day.

Oh. Will you help me with my trig, please? Pretty please with a Slayer on top?

That sounds pretty good to me.

Hush, Xand.

Fine. Give me the sheet.

I love you, Willow!

Yeah, yeah.

Yep, Buffy's taught me a lot of things.

Trig isn't one of them.
