Neutral face emojis, for the most part, are the emoji way of saying "meh". Their vacant expressions or relative indecisiveness are perfect for when you just feel nothing about the situation. There are some exceptions here however, like the naughty looking smirking face emoji 😏 or the sleepy face emoji 😴, but for the most part - these neutral faces are a tough, emotionless crowd to please. So if you are having a meh kind of day, these emojis can help you express it.
