Anyone else get irrationally angry at their kids over stupid stuff?

My 4yo spilled juice on the kitchen floor yesterday and I absolutely lost it. Like, yelling, storming off the kind of lost it. My wife looked at me like I'd grown a second head. I know it's just juice. I know he's 4. But something in me just... snapped. This has been happening more and more lately and I hate it. I don't want to be the angry dad. Anyone else dealing with this? How do you pull yourself back when you feel it coming?
