Any stereotypical dad-esque things that Dad!Snape would also do/say/wear, but like, the wizard version? For example, if Muggle Dad is cargo shorts with New Balance sneakers, eating a can of baked beans over the sink, obsessively checking the thermostat, etc., what's some classic Wizard Dad!Snapeness? PS I love your headcanons, thanks.
Thanks :). These are fun to think about and write out.
You know the stereotype of dad’s reaching for their shotguns when they’re daughters start dating? That but with a wand, though I feel he’d try to be more subtle about it than most dads. Keeping this wand in his sleeve as he glares at his daughters date with an expression that clearly says, hurt her and I will make your life… Very…. Difficult. Snape would not like it at all when his daughter starts dating.
He is adamant he does not make dad jokes. Except he does, it is a force he cannot stop they just slip out. When he realises he’s made a dad joke he is mortified.
He under no circumstances wants his kid to get on the back of a broomstick that someone else is flying. It is bad enough they have to learn to fly at Hogwarts in the first place and if he had his say they would never even touch a broom but he at least wants them to be the one in control of the, in his opinion, very dangerous contraption. He often goes off on tangents about how dangerous broomsticks are.
One that magical kids everywhere will never understand is why dads keep an almost obsessive monitoring dads do of the amount of wood/coal left for the fire, especially when they have magic and they can just get more. Relying instead on heating charms that don’t last long and have to be recast frequently. Snape takes this to extreme and even goes as far as rationing the amount of fuel used (probably a trait left over from growing up poor in a household where magic was forbidden).
Stereotypically the expression Merlins Beard is used mostly by dads in the wizarding world. This is probably because it is like swearing without swearing and you don’t swear around kids. Snape adopts this expression more after becoming a father. Also if his kid swears he will glare and say “Language.” in a warning voice.
