I would say it's somewhat similar to buggie; sometimes Mama will *insist* upon something, others she'll strongly suggest it, but mostly she just lets me make decisions with a bit of guidance from her.
However, this is all because she chooses to allow me that freedom. If, at any time, she were to decide something, I would have to go along with it. Thankfully she's a really nice Mama; depite having 'total' control over me, she chooses not to exercise it unless absolutely necessary.
I should point out I'm the same way when I'm babying her; I let her make her own choices about most things, giving my input, but if I ever feel very strongly she should/shouldn't do something, I'll put my foot down. There are times when Mama knows best, after all!
Edit: Oh, and I don't necessarily always want to obey Mama; if I don't, I can kick up a lot of fuss and there's nothin' Mama can do to stop me! 'Cept put me in time out...
