Do the preparation task first. Then read the text and tips and do the exercises.
1. You don't need to write complete sentences for text messages.
2. Use abbreviations like LMK (= let me know) or use emojis to save time writing.
3. You don't need to use full stops (.) at the end of messages.
4. Say how many minutes you think you'll need, e.g. I'm running 10 minutes late.
5. It’s good to say sorry and sorry again, but you don't need to say sorry in every message.
