Provide the theme summaries for the following conversation: 

Laura: Hello Ethy, in the paper they say Peter's lecture starts at the cemetery. Is it correct? Last time it was at the council house.
Ethy: It is correct. Peter decided to start there because we noticed last time a few people just didn't make it that far. So he's reversing the order.
Laura: I see! We want to be there. Ed is quite curious. Will you attend?
Ethy: Of course. I know his text by heart but I have to be at his side all the time. With medications etc.
Laura: I suppose he also feel more confident when you're around.
Ethy: Very much so. In fact we are together most of the time. It does start to sap my energies. But - no choice! Will you be attending?
Laura: Just told you we both would.
Ethy: Nice of you! Peter will be happy to see you. But certainly you know everything he's going to talk about.
Laura: Not exactly as he always finds out new details. It will be new to Ed though.
Laura: Shall we have a drink afterwards?
Ethy: That depends on Peter's condition. Only if he's not too tired. Then he'd only want to go home.
Laura: Sure enough. Just a suggestion. So let's hope the weather keeps and Peter's lecture will be well attended.
Ethy: I'm sure it'll be a success again. So I'll see you both at the cemetery?
Laura: Yes. Ta ta!

Summary: 
Laura and Ed will meet Ethy and Peter at the funeral. Peter will read a lecture at the cemetery and not at the council house.They will have a drink together after the funeral if Peter is not tired.
