Final answer:
If you need to inform your mother that you are heading to the hospital because a friend is unwell, it's important to convey urgency and reassurance. You might leave a note or send a message detailing your action and promising to update her as soon as possible.
Step-by-step explanation:
Communicating urgent messages to family members, especially when they are not home, is an important skill. If you need to inform your mother that you are leaving for the hospital because a friend has called and is not feeling well, it's crucial to be clear and provide sufficient details.
For instance, you might write a note or send a text saying: 'Hi Mom, just letting you know that I'm heading to the hospital because [Friend's Name] is feeling unwell and needs me. I'll update you as soon as I can. Please don't worry; I'll be safe and call you later.'
These types of messages convey the situation's urgency and reassure the recipient that you will follow up with more information. It is an act of responsibility to keep family members informed about such unplanned circumstances, ensuring they are aware but not overly concerned.
