How to write the title of square dance circle of friends

It's the first time this year to take such a leisurely walk in the morning. I watched the aunts dancing in the square dance in the park, and their faces were filled with carefree and happy smiles. Suddenly, my mood was infected by their happy emotions. Recently, I'm often depressed, and I don't know what's bothering me, but I'm just very depressed. I came out for a walk this morning and felt happy in an instant.
