And how important would it be to the students as well, and to him being able to progress with a comfortable, normal life? Because every witch/ wizard in the UK goes through Hogwarts. The first year after the war, he starts, and the students all come home at Christmas or in the summer and their parents are all ‘WOW you’ve been taught by HARRY POTTER what was he like?” And all these students who are totally over it already like “I don’t know, just… he’s just Professor Potter. He’s just Harry. He makes shit jokes and hands out chocolate in lessons. He’s just a really great guy.”
And over the years it stops being people yelling ‘The Chosen One’ or ‘The Boy Who Lived’ in the streets. He goes in to Diagon Alley with his family and everyone’s like ‘Oh my god, Sir! Hi! Look, it’s Professor Potter!’ And no-one wants to know how it felt to die or what vanquishing Voldemort was like- they want to tell him how their doing, and chat with him about how they want to go into the Aurors or Dragon taming, or what they’re doing now. They want one of their favourite teachers to meet their kids, reminisce about old lessons.
But of course, everyone still knows it’s Harry Potter. And it becomes like a thing among the students, whenever anyone feels low on confidence or like they’ll never achieve things in life, and someone’ll cut in like ‘Of course you can. Harry defeated the greatest Dark Wizard in memory, and he’s a massive dork who’s a little bit frightened of his wife and kids, still trips over the trick step, didn’t get the date he wanted to the Yule Ball and spills pumpkin juice all over his robes regularly. He’s human just like you, and if he could do that, you can sure as hell make the DMLE if that’s what you want.”
Like Harry and Neville being constant reminders to all their students that heroes are just people- just real, normal, faulty people.
(And then can we also have Ginny Weasley, taking some time off from playing professional Quidditch so she comes to do a few years as the flying coach. And her first year Harry goes down to the pitch with a few of the 7th years he has under his wing, and Ginny being, as always, vaguely terrifying but in an incredibly attractive way. And all these 7th years just gaping at her like ‘Woah. You are married to her?!” And Harry just massively smug like ‘Yeah, I know right?’)
