You know what's amazing? We can feel lots of different emotions, and that's totally normal! Sometimes we're happy, sometimes we're sad, and sometimes we're even a little bit angry.
Can you imagine having four faces, each one showing a different happy emotion? It's like having four little friends inside your head, each one feeling something special!
When we feel happy, our faces light up with big smiles. But did you know that there are lots of different ways to feel happy? We can feel excited, relieved, proud, or even just plain silly!
When we see someone else's happy face, it can make us feel happy too! It's like happiness is spreading from one person to another, like a big happy chain reaction!
