I would be freaking out like crazy inside but I would talk to them for as long as possible and the get pics, autographs and ya i would give them my number too! then when i leave i would scream so loud with happyness!!!!!!!!
I would nose-bleed and pass out right there. And have little Gilbirds flying over my head. Of I'll have to wake up only to see Tamaki and Kyoyo to nosebleed and pass out again. The picture (wallflower) basically sums up how I'll react
