HYORIN SISTAR, just a few months short of their three-year anniversary, got a shout-out on twitter from bandmate Hyorin. She tweeted the above picture with the caption: "It’s already been 1,000 days since SISTAR has been with you! You don’t know how sorry and grateful we are. Please continue to love us for the next 10000 days and 1000000 days!”  The set of four images, show a range of expressions, starting with a simple pout and working it's way up to a big grin. Points awarded for dynamic photo taking! Do you share in Hyorin's excitement?
