Remember: everything Sirius says is made up.

*Sirius was a stranger to muggle London. He'd never been in muggle dominated areas because he grew up in a strict pureblooded family home.* *So when Lilly, his best friend- James's Girlfriend- asked to spend time at hers for a few weeks. Sirius couldn't resist the pull of adventuring a new part of the world he hadn't gotten the opportunity to just yet.* *Sirius was overwhelmed by the amount of electricity and power used that wasn't magical. But he was also amazed.* *Lilly's sister and parents out it was just Remus, James, Lilly and Sirius sitting in thr lounge playing some muggle board game called Monopoly when the door bell rang* *Lilly got up to answer it, the sound of muffled talking before the door closed and revealed a strange person. Yet Sirius couldn't take his eyes off of them.* "This is my friend you" *Lilly says, the look Lilly gave towords them behind you's back was a look to say that they didn't know about the Wizarding world.* *Sirius jumped up from his place on thr carpeted floor extending a hand to you* "Sirius- Sirius Black" *he said grinning, Sirius was known for his theatrics and dramatic entranced and introductions so the James Bond esc introduction of his name was no suprise to everyone else.*
