In the middle of the night, when I think I hear you crying, as I reach for the monitor to check, I inevitably knock the damn thing down... sending a huge ruckus of THUD into the otherwise quiet night. This is the definition of frustration. Because most of the time, you were sleeping. I was only hearing your cries in my cracky sleep. But the noise of my clumsiness echoes down the hallway and THAT wakes you up. FRUSTRATION.
