I run for fun

I run as often as I can, and I do it for fun (as the title suggests), but it seems like a lot of people can't understand that. Does anyone else feel that way? What is it about running that makes people think I'm doing it for some other reason. Is it because running is so "horrible" or is it because I'm a size 10 and I must be trying to lose weight? Why is it that lots of times when I mention running, people start giving me ideas of other exercises that burn more calories? Sure, I'm glad that I'm down from a size 14, but that's just a happy side affect. I don't run to lose weight, I don't run so that I can eat junk food and I don't eat junk food because I run. Why is it so weird to say that I didn't want to skip a run, so I ran earlier than scheduled so I could go to Burger King with me brother? I run because I like it, and I eat junk food because I like to and the two subjects are unrelated. I'm ranting, I know, but this subject makes me mad.
