Interruption
Pinkie Pie was never predictable. She was the chaos butterfly's equine cousin, who could appear at any time. She didn't react how regular ponies did, either; she would explode in excitement at mundane news, or nod sagely at unpredictable events.
For three days now, Rainbow Dash had been trying to get away from her. But, by hat or by fireplace or by giant trampoline, Pinkie always found a way back.
It wasn't that she minded. She couldn't help but smile, every time. It was just...she was thinking of how to tell her how she felt. But she kept being interrupted.
