"Glass half full or glass half empty". The question refers to whether you are an optimist or a pessimist. Do you see life in a positive way: "glass is half full", or in a negative way: "the glass is half empty"? An important distinction. But another question to ask is this: "What is your glass filled with"? The content of the glass is important because when the glass is tipped over and the contents spilled out, they end up all over the place. A glass filled with water can be easily cleaned up with a dry towel. A glass filled with motor oil causes a bigger mess and a mess that may last for a while. A person filled with love and respect and a positive attitude toward others is not exempt from being spilled over. But when they are tipped or knocked over, the love and respect and positiveness spills out all over other people. When a person is full of bitterness and anger and resentment and negativity is spilled out, then that is spilled on to others, as well. And if the glass is full to the brim of these things, when the glass is merely jostled a little bit, the contents get out and impact others. We may not be able to control the volume in our glass but we can control the content.
