Penny had grown up a muggle, before learning about her magical heritage... and she adored learning about how the magical community viewed the muggle world..

Raising her hand in the air, "Well Professor, Muggles love their cars, I mean, their cars are almost like a status symbol - like how big or important a person is or how much money they have in the bank.... I think a good majority of the muggle world travel to and from work in cars... More than Public transport or Bicycles"...

Penny could think of more examples, but thought she should let her classmates have a go too.
