You're gonna love this one. Quick tip, always use capital letters for days, months, cities, and the pronoun I. So it's Monday, not Monday, April, not April, Madrid, not Madrid, and always I, never I. Here's the thing. In English, these words are proper nouns, so they start with a capital letter. Y el pronombre también, aunque esté en medio de la frase. This is important. A lot of students forget this in chats or homework. Example, I'm going to Barcelona in July to see my favorite singer live. Voy a ir a Barcelona en Julio para ver a mi cantante favorito en directo. Keep practicing and see you tomorrow.
