Empathy and sympathy are closely related, but both have different connotations.
Empathy is about feeling what someone else feels, whilst sympathy is about action. When you meet someone with empathy it isn't difficult to see they are sympathetic too. Someone who is sympathetic but not empathetic, may fail to connect emotionally with others.
Words express thoughts, but it’s acting on those words that show that we care. As the saying goes 'actions speak louder than words' and I believe that to be true.
A little bit more about empathy:
Empathy is also the building block to relationships and that’s what relationships need to thrive on. Everyone can sympathise but not everyone can empathise.
