I love the song "Happy" too Otter - I can dance around in my lounge listening to that, for no reason, what so ever - so you're not alone.

I think people are quick to assume if they know we have an MI that it must be "this" or it must be "that".

Well, as we have learnt, it just simply isn't as well defined as that.

Yes - I 100% agree with what you say - sometimes an up or down doesn't have anything to do with our MI.

What do I call that?

I call it "Life".
