2nd Guest. Do let me.
1st Guest. Not at all.
2nd Guest. I assure you I prefer it too.
Host. No, sit here. When you're both comfortably settled, I'll get in.
1st Guest. Oh no, please. I'm sure you never sit there. I hate to take away your own place.
2nd Guest. Do let me.
Host. I insist.
1st Guest. Please don't say any more about it. See, I'm in now and quite comfy.
Host. It's very wrong of you to be there.
2nd Guest. Do let me.
