There's no need to call me sir t-shirts.
….
"… and his exact words were… 'There's no need to call me Sir, Professor'" Lily sent a quick glare at James, who was clearly trying not to snigger, before she continued, "Understandably, Professor Snape has insisted on punishment, and the writing of this letter. He may find it not harsh enough for his liking, however, as the Head of Harry's House, it is my duty to inform you. Yours Sincerely, Professor Minerva McGonagall."
There was a brief moment of silence, before both Lily and James glanced at each other… and burst out laughing.
"Poor Severus…" Lily giggled, "… he just gets rid of you, and he's got Harry to contend with."
"Sirius needs to hear about this!" James was still laughing, moving over to the fireplace, "This is the proudest moment of my life!"
"Oh, so when he was born, walked for the first time, got his letter to Hogwarts…. None of those matter?" Lily smirked as James clearly ignored her, already sticking his head into the fireplace to talk to Sirius.
It didn't take long, before James re-emerged, a beaming grin on his face. "Sirius is on his way… we need to send Howler to Harry. Lure Sni- Snape into a false sense of security, make him think that Harry's going to get into trouble, and then it's just us congratulating him!"
"Or…" Lily sent him a wicked smirk, "… we could do something else?"
"… I'm listening, oh gorgeous wife of mine?"
…
"Nothing." Harry muttered as the flow of owls carrying the morning post slowed to one or two, with no sign of Hedwig anywhere, "Still nothing… Professor McGonagall said she'd written them a letter though?"
"I don't know why you're so worried mate…" Ron chuckled, buttering up another piece of toast, "… My mum never hesitates to send me a Howler. Maybe yours found it funny? McGonagall did, you could tell… maybe she never sent the letter?"
"Professor McGonagall isn't the type to do that." Harry practically slammed his head down on the table, "They're doing this on purpose… they're making me sweat before the Christmas holidays, and then they're really going to let me have it."
As Harry fretted, teeth nibbling on his bottom lip, Hermione noticed something very interesting…. Professor McGonagall and Professor Lupin had both received packages from a pair of very familiar owls.
Both smirked at the note attached, before shielding them from the other Professors… it was all rather suspicious.
…..
The week before Hogwarts broke up for the Christmas holidays, another Quidditch match was scheduled.
More specifically, another Gryffindor vs Slytherin match… with Snape's guaranteed appearance.
And because Harry was the star player for Gryffindor, it was guaranteed that his parents would be there too, along with Uncle Sirius.
He could see them as he flew past, eyes constantly keep a look-out for the snitch, only briefly glancing over the family.
They didn't seem angry with him.
Suddenly spotting the snitch out of the corner of his eyes, he dived straight for it, catching it in his gloved hands as everyone cheered and whooped in glee.
"Harry Potter catches the snitch!" Lee Jordan announced, "Gryffindor win by over 60 points and- HAHAHAHAHAHA!"
At Lee's sudden cackle, everyone turned their attention to the teacher's podium, where four familiar figures were standing up.
James, Lily, Sirius and Remus were on their feet, clapping at the victory for Gryffindor… but it was the t-shirts that caught everyone's attention.
Written on the t-shirts, was the phrase 'There's no need to call me Sir, Professor'. Through impressive charms, clearly Lily's work, the text on the shirts were colour-changing and glowing, making them impossible to miss.
Lee couldn't comment on it due to him laughing too hard.
Snape had stormed away already, pushing past Professor McGonagall as his face burned with the humiliation.
What he failed to notice however… was the slight glow coming from underneath the Gryffindor Professors' robes.
