Rats have an unwarranted bad reputation. However, rats have been known to exhibit sympathy. Scientists set up an experiment in which a rat would pull a lever to be rewarded with chocolate. If the rat pulled the lever, another rat in the section beside them would be drowned. It was revealed that most of the rats refused to pull the lever and receive the chocolate once they realised that the other rat would suffer. It was also revealed that the rat’s who had gone through the near-drowning experience were more likely to protect the other rats.

Sympathy’s easy. You have sympathy for starving children swatting at flies on the late-night commercials. Sympathy is easy because it comes from a position of power. Empathy is getting down on your knees and looking someone else in the eye and realizing you could be them, and that all that separates you is luck.
If you want to be loved, start loving others who need your love….If you want others to sympathize with you, start showing sympathy to those around you. If you want to be respected, you must learn to be respectful to everyone, both young and old….Whatever you want others to be, first be that yourself; then you will find others responding in like manner to you.

I know how you feel when you’re alone, lying on your bed, looking at your phone as if it’s meant to bring you peace from all the demons tugging at your head. You ask yourself; who in the hell will love me? And you should always remember no one will, unless you love yourself.

The Aquarius Moon is an enigma that very few understand completely. As they’re capable of great sympathy, they, like Gemini Moons, lack empathy greatly.
This placement is the greatest example of the difference between Sympathy, and Empathy (which, in my opinion, Scorpio would be the most empathic moon sign lacking sympathy).
They’re humanitarians, yet are capable - and almost bound - to cause great discourse between their friends and those they aquatint themselves with, not unlike the Scorpio Moon.
