Emotions (Metaphor Challenge)

Tough Metaphor Challenge by @Denis Sazhin / Iconka.com

@Vadim Carazan challenged me to depict metaphor for "emotions"

So here's the challenge:

1. You can leave a comment to this post and I'll give you a tough (in my opinion) metaphor to develop.

2. You make a rebound of this post with the icon you create based on that metaphor.

3. Whoever comments you gets a tough metaphor from you, and they do a rebound of your post with their icon.

4. And it goes on till we're done playing.

--------------

Some basic rules:

1. No text preferably. I feel like using text in icons is sort of an easy way out.
2. Keep it simple. It's supposed to be an icon, not a concept illustration.
3. Keep it civil, keep it smart.
4. I think feel free to share your variation of the same metaphor in the comments, if you want to.

Let's get that brain working!
