acting like a kid can be really fun or even embarrassing, but either way it's cool because acting like a kid is fun. it's fun to just be silly and goof off and dance like no one is watching you and sing like no one is listening. i do it all the time even in my head, i will hear a song in my head and start to sing along out loud and i will dance around to it too or move my head and move my torso to the music.
