The Restricted Collection: #5: Guideline - Write a story that is in present tense.
Albus Dumbledore sits in his office, and all is quiet, save for the occasional tinkering with a trinket on his desk. Even the portraits know to respect when Albus wants to think. His mind is swirling with ideas, and he must sift through them and choose the best plan to carry through with. The one that will keep him from hurting too many people like before.
He knows sometimes he chooses the wrong idea by mistake, so he must think very carefully about this.
And even then, he might choose the wrong one yet again and harm the people that he loves...
He sets down the little instrument he had been fiddling with just before. This job is getting to be too tiring for him, but he knows he must trudge onwards until he is fulfilled.
