Because an emoji is worth a thousand words.
When your toddler won't stop harassing the cat:
What it means: "You're going to need to get the cat out from under the bed when you get home."
When you finish doing your teenage boy's laundry:
What it means: "I have seen things. Things I can't unsee."
When you get a whiff of your baby's butt:
What it means: "This one's your turn."
When you have to break bad news:
What it means: "Your daughter found the scissors."
