Severus walked briskly into the small grocery, keeping a firm watch on the energetic Gryffindor beside him. The man practically bounced with unbridled excitement, clearly not understanding just how insignificant a trip to the grocery truly was. The absurdity of it annoyed Severus to no end, but he bit back a sharp reproach. Black had, at least, possessed the decency to redress in muggle clothing like Severus had requested. Wearing a pair of simple trousers, along with a Weasley sweater with its embellished S, Sirius looked every bit the muggle.

"Hello."

An elderly woman called out to them from her perch at a checkout, her wrinkled face smiling brightly as she gave a little wave. Lilah- that was her name, Severus thought. A sweet old grandmother of a person, always chatting away with her customers as if they were her lifelong friends.

Severus gave a curt nod, having always been uncomfortable with any kindness directed at him. It was a foreign feeling, and he knew enough to know that such niceties weren't for people like him. He was born for labor, not for love. Black, on the other hand, ate the affection up like one accustomed to being doted on.

"If you're quite done," Severus muttered, "Let's go."

"Haven't you got the kindness to smile at a sweet, old lady?" Black demanded, looking mildly offended at Severus's lack of manners.

"I neither want nor need a lecture from you." Severus hissed, grabbing a trolley.

"Calm down." Black replied. "I wasn't lecturing you."

"You could have fooled me." Severus countered, heading down the first aisle they came to. Which just so happened to be the candy aisle.

Unbeknownst to many, Severus had just as big a sweet tooth as Albus, if not bigger. Walking a feet down the corridor, he grabbed a few packages of Oreo's and carefully laid them in the cart so they wouldn't crumble. There were few things as vexing as broken cookie bits.

"What are these?"

Severus looked up, spotting Black with a large package of cherry Twizzlers. The man seemed amused, poking at the plastic packaging as if he expected it to yield any real explanation.

"Twizzlers." Severus said gruffly. "It's cherry licorice."

"Disgusting." Black grimaced, placing them back in the correct spot. "Though they do kind of look like fake wands."

"I assure you, they're candy. Nothing else." Severus drawled, tossing in a huge bag of M&Ms.

Thankfully, Black seemed to realize Severus was in no mood to converse, especially so with his former enemy. The Marauder kept silent throughout the space of an hour, making little to no noise as Severus filled his cart with the essential staples of; milk, egg, coffee, bread and butter.

It wasn't until Severus was getting ready to check-out that he realized his nemesis was gone. Hastily chucking a large package of toilet paper into the cart, Severus hurried off in pursuit of his renegade houseguest.

Cursing Black under his breath the entire time, Severus finally located the escapee in the toy aisle, looking down the barrel of a loaded nerf gun. Severus came up short and waited, hoping against hope that Black would pull the trigger and shoot his eye. Alas, it was no so. Having felt eyes on him, the Dog brandished his gun in Snape's direction.

"What does this do?"

Severus didn't get much chance to answer before a foam pellet flew through the air, pegging him directly in his eye. Swearing under his breath, he rubbed the offended eyes and glowered as best he could at the shell-shocked Gryffindor.

"I didn't know that would happen." Black insisted, biting back giggles.

"We're leaving." Severus declared. "Put your toy away."

"It's a toy?" Black asked, decidedly embarrassed.

"Indeed." Severus agreed, rubbing his eye.
