Rolls change per situation. Thats like asking what is a cookie for. You can say basics.... for eating. Or you can dive deeper. For fun... deeper.... for Love..... now we are on a topic we all enjoy. Love. Is there only one kind of love? Do you love your mom as you do your best friend? Do you love your dad as you love your boyfriend? What are relationships for? Why do we even communicate? Are words the only way to communicate? What is yin and yang? Do we need balance? Why are you here on earth? The answer is Love.
