The sound that makes me punch babies

We all have one. And mine is the sound of rain on tarp. Apparently it rained last night. First of al, WTF? No one said anything about rain. But whatever, it's all good. I love the rain. But not when it bangs on tarp. And not at 4:00 AM. And not when I have no idea what the sound is. And not when it prevents me from falling asleep so I have to turn my fan and my audio recording on Prince Capsian. And not when I have no idea where my headphones are so I cann't even use those to block out the sound. And not when I have to get up early to teach music and chorus and theater to a bunch of middle school kids. Rain on tarp=no bueno in my book.
