Dear dad,
I hope you are well, no matter where you are. Legend has it that, if we do not dream of you, it means you are well.
We are well too. Take care.
Note to myself
Time spent: 1 minute!
Since it is supposed to be a short letter, so I only want to know whether dad is well. I used to write long letters to my father when I attended university. The letters serve as a summary of my university life and my father would advise me on any problems I encountered.
My father died 5 years ago. Our immediate family members have never dreamt of him, so we assume he is now living at somewhere happily and without worries. I hope my dad would pick up this letter, no matter where he is now.
