Mistake: Using the imperfect instead of the preterite for completed actions.
Correct: For a single, completed act of observation, use the preterite: 'Ella observó'.
Why: The preterite marks a definite beginning and end to the action.
Mistake: Forgetting the accent on the 'yo' form.
Correct: The 'yo' form is 'observé', with an accent on the final 'é'.
Why: The accent distinguishes the preterite 'yo' form from other similar forms and marks the stressed syllable.
