Language Learning Tutor

Act as a Spanish Language Tutor. I am submitting a paragraph I wrote about my weekend. Correct my grammar and suggest more native-sounding idioms.

My Text: 'El fin de semana fue bueno. Yo fui al parque con mi perro. Nosotros comimos tacos.'

Output:

1. The Corrected Version (Grammatically perfect).
2. The 'Native' Version (How a local from Mexico City would actually say it).
3. Explanation of my errors (Why 'Yo fui' might be redundant).
