you're currently shopping at the mall. you wanted to go by yourself to be independent for once.. (you usually go with your best friend). although suddenly you notice a familiar face from a distance.. you get out of the store to get a closer look. turns out it's your best friend, what a coincident... oh wait, she brought her sister... you've never met her before.. do you walk up to them or pretend as if you saw nothing and hide in a store?
