When I was at Warped, Kellin walked past me and I yelled his name, and he turned around and I asked him for a picture, and made a sound like he was annoyed and put his hand up and said "Talk to the hand". Then after walking a few steps he turned around laughing and said "I'm sorry I think I'm funny but I'm really not, I love you." And then he took a picture with me and talked to me for like 10 minutes. He's so incredible I can't even.
He has the same sense of humor I do, I just love it so much. :)
