You`re staying with your friends in britain you were planning to go to cinema together this afternoon but your plans have changed.leave a note for your friends 1)apologise for the change 2)explain why you can`t go 3) suggest another day

Hi Tom,

I am really sorry but I'm afraid my plans for today have changed unexpectedy. I have a little family emergency, and I need to rush to the hospital to stay with my sister. I still want to see the film, so I would like to suggest going to the cinema on Saturday.

Please let me know whether it suits you or not.

Cheers,
(Your name)
