Quote context

[...]

- My visit to you hasn't been wasted. I've found a rare and beautiful butterfly, Euvanesse antiope. It's very unusual in England. Don't you think it's beautiful, Mr. Gray?

- Yes, Lord Henry, very beautiful.

- You may sit down now, Dorian.

- I'm glad you met Lord Henry after all.

- Are you glad, Mr. Gray?

- I'm glad now. I wonder if I shall always be glad.

- Always? That's a dreadful word. It makes me shudder to hear it. Women are so fond of using it. They spoil every romance by trying to make it last forever.

- The only difference between a caprice and a life-long passion is the caprice lasts a little longer.

- But I believe our hostess has appeared.

- You're just in time, darling, to witness my signature to Dorian's painting.

- Could I sign it too?

- Well, I think you're entitled to. Since you haven't missed a sitting. Here.

- G for Gladys.

- Which do you prefer, Gladys, Dorian Gray or his picture?

- I like Dorian best.

- You prefer him today, my dear, but when you're a young lady and are turning all the handsome heads in London, you may prefer the portrait.
