Dear friends,
Do you remember your first day at a new school or in a new area? How about the1when your family2 to a new state? Ugh! What about the feelings of being a stranger?
Then, with time, you find someone who likes 3you like.  Friends are great gifts in life. I have good friends too,  but not because they are completely(完全的)4 .Sometimes they talk too much; sometimes they need me a lot. I know I ask too much of them. I hope my friends, like my father,5about me a lot.
I once told my friends to give me all their love and be generous and gentle. I told my friends, in other words, to love me6I loved them.
They didn’t7 me at first, but then they became kinder. My love for them slowly made them learn to8 friends. They learned to love others and 9the idea that LOVE is part of life.
If we listen to and try to understand each other, love10.We should work on it, even if it’s hard at first. A true friend loves US at all times.
Your friend,
Jesus
