Who are these strange people that come up to talk to Harry Potter on the street?

Answer 1

Just random wizards and witches that have heard of Harry Potter, but who don't know him personally - and of course, Harry Potter doesn't know them. The idea is that Harry Potter is famous, due to his defeat of Lord Voldemort when he was one year old - of which he remembers hardly anything, and (at first) has no idea how it might have happened.

Answer 2

Oh honey, those "strange people" are just wizarding folk from the magical world of Harry Potter. They're not strange, they're just not from around here. So next time you see someone in a cloak with a wand, just remember they're not lost, they're just on their way to Diagon Alley.

Answer 3

In the Harry Potter series, the strange people who approach Harry on the street are typically members of the wizarding world, such as witches and wizards. They may be acquaintances, friends, or even foes from Harry's adventures in the magical realm. These encounters often serve to advance the plot, introduce new characters, or provide information crucial to Harry's journey. Harry's interactions with these individuals play a significant role in shaping his understanding of the magical world and his own identity as a wizard.
