I know you are interested in [oil painting], so I’m sure you’ll be interested in [Mr. and Mrs. Lin dun]! They are coming here to supper [next Sunday night, October the twelfth], and we’d like you and [Walter] to come, too.

They have a wonderful collection of [oil paintings of various stages]; and I understand that Mr. Lin Dun is quite an authority on [oil painting]. I’m sure you and Walter will thoroughly enjoy and evening in their company. We’re planning supper at six; that will give us a nice long evening to talk.
If I don’t hear from you before then, I’ll be expecting you on the [twelfth]!
yours,
Li Ming
