Un peu d'anglais du jour

Yesterday it was a very good day! First, i've learnt I studied (saying "I studied" sounds more natural)  English with my teacher on the a website. (If you are going to name the website, you can say "the website" for example: "I studied English with my teacher on the website italki.") Then i've I met a friend at the opera near Galerie Lafayette (I don't know what this is, but if it is the name of a place, the first letter should be capitalized) in Paris. It was a great moment, we ve eaten ate out in a good restaurant . The food was very delicious. After, I eated ate at my parent's home with my brothers and sisters. 

Very good! Just remember to capitalize proper nouns (the names of things like cities, specific places-you wouldn't have to capitalize "bank" but if you say the name of the bank, that would be capitalized, or languages). "Eat" is an irregular verb so it's past-tense form is "ate."
