Spring Street in Fitzroy

The other day I was having some lunch outside the state library, when a guy came up to ask for a cigarette. While I was rolling it for him he started asking me about Spring street in Fitzroy. I told him I didn't know it. He did not like this answer. I was then, very abruptly, told to go to Spring Street in Fitzroy. Do you know what you will learn on Spring Street in Fitzroy!? How to build old fashion houses! And with that he thanked me for the cigarette and walked away.
