When I was a kid, there was a PSA on TV from time to time that went something like this: "When you feel yourself getting tense. Stop. Two. Three.... Breath. Two. Three.... Think your way to sense."
Despite the cheesy phrasing, timeouts are a good thing for adults, teens, and kids alike. They can help us calm down when we're frustrated. So, the next time you're feeling angry, take a break, count to five, or walk away from the person you are frustrated with until your anger dissipates.
