A smile is the soul reaching out to other souls. It is the reflection of soul's joy. It is caught when eyes meet. It is natural to smile when smiled at. So smile and bring joy and light to other souls.
I can't stop laughing! For those who don't understand a vegetable can be a person in a vegetative state which is a brain dysfunction where a person shows no sign of awareness and thus is in a wheelchair meaning it's a cannibal joke.
