Well... today I took my final in my math class (8-10 am ) and on my way back to the dormatories (real life, what else can I be talking about?) and there were these teenagers walking slow, looking at a map of the university. So... After I passed them I asked, "Can I help you? Are you looking for somewhere?" One of them said then pointed at the words on the map "We are looking for the University Mall"  then I pointed at a large patch of grass that was right in front of everyone! This is a mall, a large patch of grass that well  people do stuff. I used the mall in Washington DC as an example  You see that grass area? Thats a mall.  They said thank you and I continued to walk to my dorm...  Then I looked back and more of their friends came back and as
darn didnt finish... but when I looked back they were laughing with their friends so that means they thought that there was an actual shop!  we all learn eventually! 
 I can be wrong though, I mean... there can be a store right in front of my dorms without me knowing!  its invisible.
