Answer:
just write a letter to your friend on what emotions took place with you when you saw the orphans and how did you react.
Explanation:
-explain if you were sad? happy? or joyful.
-how you will help them if you felt sad.
- since this is a letter to a friend write an informal letter ( meaning that you can use dude, brother, sis but don't use Hi just only use hello!) you don't want a letter to you been sent from a friend like " I am writing this letter to inform you the utterly disagreeable and dreadful news which I witnessed on my visit to the orphanage" so use simple words.
