The way a person can make you feel small and not know that they do. Your confidence can be torn down by the simplest things and can make you feel paranoid and self conscious. You can feel worthless and non important. But they've said nothing and it can all be your thoughts but then it could be reality.
But then knowing you've made someones day can make your day. It means you matter to someone.
So take a chance, you never know were it can lead you, it may be a bad choice but then we have something to learn from. Thats life
