That's really nice to know that an anti finally gets a chance to see SNSD for real and then change their opinions about them. Most, if not all instances are like that, people tend to judge something or someone without seeing it for real. I'm happy that your friend got the chance to SNSD for who they are, live and alive.
Yay! Another SONE-in-the-making!
Even though I'm jealous, because I am the SONE not her, so I have the priority to see SNSD xD I still feel proud of our Girls' Generation!
