words have a huge impact on people.
it doesn’t matter whether you mean it or not. it doesn’t matter whether you say it intentionally or not. it doesn’t matter whether you’re drunk or sober. it doesn’t matter whether you’re joking or not. what matters is that you already said what was on your mind. the things that you say today, that person can remember it for the rest of his life. you can wish to go back in time but it’d be pointless. you could be the reason for someone’s depression or wish for amnesia. 
but don’t forget, you can also be the reason for someone’s happiness.

think before you speak.
