"A veces dices cosas con una cara sonriente cuando en realidad las dices con una cara triste"

Simplified Meaning:

Sometimes, you might pretend to be happy and smile when you're actually feeling sad or upset inside. Imagine you go to school and your friend makes a joke that hurts your feelings, but you laugh along with everyone else so you don't seem bothered. This can happen because people often try to hide their true emotions to avoid showing weakness or making others uncomfortable. For instance, in history, many leaders have put on a brave face during tough times to keep their followers calm, even when they were worried. Similarly, you might tell a friend you're okay with something that actually upsets you because you don’t want to cause trouble. The advice here is to recognize when you or others might be hiding true feelings. It's okay to share how you really feel with people you trust, to avoid misunderstandings and get support when needed. This way, you build stronger, more honest relationships.
