I like this picture for what it shows us. I have always said Never make a permanent decision based on a temporary emotion. We can become angry, upset and frustrated. When we are in this state the way we see the world and others in it can change. It is important to allow ourselves time to cool down and make decisions with a clear mind and a clear heart.
Words that we say can cause a lifetime of hurt, even if apologized for later. We can cause someone to have fear and a complex for the rest of our lives because we let our emotions get the best of us. We can forever change the way they look and feel towards us for letting our tongue get ahead of our head. It may feel like the right thing to do at the time, but do yourself a favor and Never make a permanent decision based on a temporary emotion.
