You feel guilt when you're not necessarily in the best mood and you say to your fans "No, I don't want to take a photo," or you're not as happy or bubbly as they probably thought you would be. I've had to remind myself that's okay. No one's forcing me or any other celebrity to take time out of their day to say hi to these fans or do these things. There is a sense of guilt that you can feel sometimes for not meeting their expectations, but that's kind of wrong for me to think that way, because I am a person.
