Day 38: Slugs

I wonder if slugs communicate with each other. Do they talk about their feelings with one another, or do they simply exist while they have enough to eat, and simply cease to exist when they run out of food or time?

I wonder if humans, left to their own, in wilderness, would be the same as slugs. How is it that we become so complex in our emotions, that we discover layers and layers of different feelings? In addition to our emotional complexity, we also add the complexity of good manners. We say things we don't really feel so that we don't hurt someone's feelings (or sometimes, our own feelings). If we were to agree on National Slug Day, would some of our emotional entanglement untangle itself?
