Dear Alice,

I have just got some good mews to tell to you.

I win a national prize for painting last week.

My father was so pleasing that he suggested

I go to England for a holiday. I’d like to staying

There for half a month, visiting place of interest

Or practicing my English as well. We’ve been

Writing to each for nearly a year now. I have

often dreamed of talk face to with you.

I imagine you’ll be at vacation yourself by that

Time. Perhaps we could go out to do some

sightseeing together.

Best,

Lily
