Putting on a front is a common phrase used when someone is pretending to be something they are not. It is often used negatively, as a deceptive tactic to hide one's true feelings or intentions. Interestingly, antonyms for putting on a front include words like "honesty," "sincerity," and "authenticity." When we are authentic, we are not putting up a façade or pretending to be something we are not. Instead, we are genuine in our thoughts and actions, allowing others to see us as we truly are. Likewise, sincerity and honesty are qualities that promote open communication and trust, without the need to put on a front.
