How did Victorians behave?

Depends on his class/status:

Working class: Usually behaves like one of those street gang boys we see now-a-days. Always dirty, quite slim and you wouldn't expect much from them.

Middle class: Stands straight, sits straight, well mannered, mild tempered, a nice ''Family Guy'', quite friendly.

Upper class: Stands straight, sits straight, well mannered, mild tempered, a nice ''family guy'', friendly. They had to behave basically.

I hope it helps.
