Under my umbrella — err, Christmas tree

B: So, what did you get me for Christmas?

J: I’m not going to tell you!

B: Give me a clue!

J: Only if you give me a clue about what you got me. 

B: Ok. You go first!

J: Umm… Let me think. Oh! Ok. Are you ready?

B: Yep!

J: At first, it’s painful, but eventually, you’ll like it.

B: It’s painful, but then I’ll like it?

J: Yep, after a little while.

B: Rihanna?
