Hi Sarah,
Thanks for your message — it was lovely to hear from you! I'm doing well, just a bit busy with work.
I'm writing to invite you to my birthday party next Saturday. It starts at 7 p.m. at my place. There will be food, music and a few friends you already know. Can you make it?
Let me know if you can come, and feel free to bring someone. I can't wait to see you!
Take care,
Emma
