It only takes the tiniest thing to create a big difference. An extra spoon of sugar can make or break a cake. A minute or two to catch or miss a train. A second or two to turn a glance into a glare. A centimeter up or down a smile or a frown. A word spoken or not a question mark or a dot. A thank you a ******* a shrug a hug a coin in a collection cup a 'how are you, honestly, what's up?'
