I get this question and variations of it nearly every single day. Just now, I got an email that really is the answer. I am keeping this to reread over and over again. It's from a girl named Zita.
Keep on with your wonderful life :)
Sorry if I bothered you, I just thought you might be interested what kind of people are watching you beside the ones who make weird phone calls.
Hi Susan,I'm a girl from Hungary, I have found your blog and webcams about a year ago via opentopia.com. I was learning for my final exam at university that time and I know it's kinda silly, but it was just good watching you and seeing an entirely different life. Since I have finished school, I have been working as a programmer and I have much less time for these kind of things, but from time to time I still "visit you" and it's just comforting to see that you are still there :)
