An inconvenience can stay an inconvenience
Dropping a spoon, missing a turn or spilling a little tea does not require a speech about the sort of person you are. Pick up what fell and deal with what changed; a small mishap already has a practical cost without being made to carry a verdict on your character.

Address what actually happened
Tea spills across a table. The immediate requirements are ordinary: move anything that could be damaged, wipe the surface and refill the cup if you want more.
A minor mishap does not need an identity attached to it. Saying that tea spilled describes an event. Calling yourself incapable makes a much wider statement without helping dry the table.
This reflection does not remove responsibility. If the spill affected someone else's belongings, attend to that too. The distinction is between handling the consequence and adding an unnecessary judgment about your whole character.
Use a factual description and a next action: the cup tipped, so the table needs wiping. Once the practical work is finished, the spoon, cup or missed turning does not require a closing argument.
