15. Make the sentences informal. Change the underlined words and phrases. Use contractions or informal words.

Informal Sentences:

1. Hi Javi. I'm from Liverpool in the north of England.
2. I've got a brother and I've got a sister.
3. Who's your best friend?
4. Email me in a few days.
5. Nothing else to say. Bye.

Explanation: Informal language often uses contractions (like 'I'm', 'I've', 'Who's') and simpler phrasing (like 'Hi' instead of 'Good morning', and 'Bye' instead of 'Goodbye').
