So basically you're saying that a character that is shown to be extremely clumsy REPEATEDLY is not permanently clumsy? You said it yourself. A few other moments. For basically all of her screen time, Derpy is showing herself incapable of properly handing objects. This screen time is split over at least three episodes. The context from said episodes also implies that these are not the only times this has happened. Who knew extrapolation could happen?
All the other ponies do it well enough, and your argument is the logical fallacy of Tu Quoque. My inability does not justify hers. Especially if her fellow equines are able to handle objects.

Crappy riddle I made: There are 2 brothers. You're only allowed to see one and listen to the other. Who are these 2 brothers?
