Your headcanons are the best! ^^ So fluffy and cuddly and heart-warming, just the way I like them. Can I ask for part 2 please? Oh, and do they have children?
When Snape says Harry's full name he doesn't say Harry's middle name. Because just like Harry isn't Lilly, he isn't James either, he is himself and Snape doesn't want anyone to mix up Harry and his parents.
Snape met the Durselys only once. It ended badly. The occlumency lessons have let him see parts of Harry's childhood after all.
When Harry is mad at Snape he just starts to ignore him. It never takes long until Snape apologizes to him after that.
Harry is good at baking. He bakes a birthday cake for Snape every year and Snape is surprised every year because he keeps forgetting his own birthday.
Arthur Weasly attampted to give Snape a shovel talk but Snape found it too weak. He was more satisfied with Molly's more threatening one.
When Snape's students have a particularly hard time in his classes they mention Harry, which makes Snape's mood way better and then he will go easier on them.
In general he has become a better teacher and he occasionally helps the children of Ron and Hermione with their homework.
He's a pretty cool uncle and surprisingly good at babysitting.
Still he and Harry don't want kids since they have no idea how to raise kids. Their own childhoods have been hard and they don't want their children to have a troublesome childhood because their parents didn't know how to care for them.
But if they had kids, they would make super sure to make them feel loved.
