Dear Sujie,
I’m writing this letter to thank you for being such a great friend to
me over the past few weeks.

I felt like a failure when I heard I was not accepted into the local
dance club.
I became so discouraged that I didn’t feel like doing
anything.
However, I had fun when you took me out to the park, and
the story about your disappointments helped me realize that I’m not a
failure but a learner.
Your support really helped me get through a
tough time.

I wonder if you’d like to go to a movie with me this weekend.
It’s
not much, but I want to treat you.

Love always,

Cathy
