A lot of people don't realise how much one joke or one comment can hurt someone. They say things and don't think twice while it may make someone who hears it cry for hours. Maybe you make a joke about someone's mother, but what you didn't know was that their mother passed away, or maybe you say something about someone having bipolar, but what you don't know is someone they love or even they have it and they know the affects it can have. Words can hurt, looks can hurt, gossip can hurt, you never know what someone has gone through or how much they have already taken. That one thing you say may push them over the edge. They may feel great one day, and you say one thing and it bring everything they had hidden back and ruin their entire day. I know we are all guilty of this, and no I am not doing this so you will cry if and feel bad if you have ever done it, just learn from your mistakes and watch what you say, think before you speak and especially before you act. No habbit is impossible to break. If you try hard enough you can do it, I believe in you. <3
