Moods are important to me.

Have you noticed that every time someone asks me something like "do you like ____ stuff?"
and I always say:
I don't know, it depends on my mood.
I just found that out and it's a bit scary...
But it's true.
I need to do everything a certain way when I have my mood set.
And they aren't definable moods.
Moods that are like...I don't know...
Not moods like angry or sad or happy.
Just really confusing emotions all at once.
I thought I had multiple personalities, but I don't think that's the case.
Weirdness...
Anyone else ever feel that something HAS to be done a certain way because your mood is set to it?
Probably not...but still I'd like to know! :DDD
