Easter Day

Yesterday I had dinner with family in the balcony on the balcony with family.
We drink drank some wine and had great food with (a/the) beautiful moon. (In this context, the moon is literally a part the dinner party. It is better as a separate sentence)

The moon was beautiful that night.
Otherwise, we celebrated my father's birthday before my sister and her husband leaved left.
After dinner, grandma mom was singing songs.
We shared smiles with each other.
What a wonderful Easter holiday.

Remember to capitalize the beginning of each sentence and finish each sentence with a period. Review how to capitalize titles as well.

Also, your story says "YesterDAY" but mentions the moon as if it is night time. I think 'Last night' is better.
