Dear Bronwyn san
Hello.
Thank you for your card.
Your cards always are so beautiful.
I like them.
It's with regret that I may not be able to visit to you in this summer.
Because my father had surgery for lung cancer a week ago,
My holiday will be scheduled from July 30 to August 7.
I think it difficult to visit you by that time.
His cancer is the first stage, and the surgery was successful.
And I hope he will be fine right away.
I will take the contact you again.
Please you give priority to your schedule.
I'll follow up with you.
