By Inside Out logic, this makes perfect sense

The differences between deciding not to show any emotions vs being unable to do so like due to a mental disorder or some such…  
Is it quite a big difference, it puts her in a whole different category of Feels that she might want to express her feelings like a normal pony, but might be unable to due to a condition that she can not control.  
I wonder if any doctor ponies ever tried diagnosis her? Or maybe she is just normally deadpan because she chooses to be that way? The world can only headcanon what goes on up in that noggin of hers. :p

I got an idea for my emotions…this is NSFW so I’ll spoil it.
 
My personal emotions, even though I’m a male, are all five buxom women, due to the fact that I’m more comfortable being around females. I have autism, so I get anxious quite easily, and it’s because their boobs are so huge they would press more buttons on the console than they intended to.

I can really believe this.

I thought maud doesn’t show emotion, but after reading this comic I think she does. only inside of her head of course…

The notion that Maud is inwardly angry over being unable to express her emotions explains A LOT.

@OverlordScorpion  
Not really: she’s still able to feel them, she’s just bad at displaying them.

So… Anons are quick with uploading…

@Philosopher Stone  
That makes this image potentionally kinda sad when you think about it.
 
Maud is sadness.

I love how Sadness looks like a real Maud.

Oh goodness the way the artist drew maud it makes my heart melt

So, Maud is bad-end!Riley?

This makes a ton of sense. :)

@That One Guy  
Fear, not Anxiety, but yes.

Hah, that’s pretty great.  
I never saw Inside Out but from my understanding, those are Joy, Sadness, Anger, Disgust, and Anxiety?
