A: Hello. Come in.
B: Thanks. It's been a long time.
A: Would you like a cup of tea?
A: Milk and sugar?
B: Neither, thanks. I like it black.
Tea drinking scenes! They should really be banned, not encouraged. How dull. How mundane. How static. That said, now have a go at writing up this scene, adding all the description and emotions, but without removing or adding any other dialogue. The dialogue may not be changed at all.
Write it with this scenario in mind...A and B are twins, but they fell out some time ago. Now, B has made contact with A and asked to meet up. What A doesn't know is that B is ill and needs a new kidney. A should be the perfect match. Remember, all through this rather banal dialogue exchange there is just one thought burning through B's mind: will A donate a kidney? Write it out, and see the difference knowing the emotional situation makes.
