Dialogue about dialogue

I’m remaking the list for the dialogue only story and dropping the talk in the car going somewhere.
1 is the discussion over where to put father’s ashes. There are several places and odd comments from one of the three speakers telling of how someone puts the urn away when people visit because Father couldn’t stand certain people. While this is a problem many people deal with, can it create enough tension? People need to be concerned about what will happen. We need two people to fight over where the ashes will go.
2 is the two wives after the funeral. It can’t just be a cosy chat with no tension. What happens is wife no 2 is uppity and then finds the daughter of wife 1, the common one, is the professor teaching her son and the relationship changes. The deceased didn’t know about the daughter because she was conceived in a farewell after the divorce. Where does it start however, at the get together after the funeral, or at an arranged coffee morning? I think just after the funeral when both daughter and son are there.
3 I tried the lesbian suicide and arguing with the vicar or priest about the church being more interrested in power than love but I don’t think it would get to 1500 words.
4 The two old sweethearts. The woman is brought to the get together by her son in case there is something sinister. I need to hold that suspicion until the end. Maybe at the end the woman discovers the man is rich and the keenness to get together changes to her. It’s and idea.
5 The couple are buying a carpet but argue and all their marital problems come out. Is this an apology for some misdemeanor? Does she want it simply to impress an acquaintance? this could be many layered and worth pursing even if it doesn’t work out for this competition.

By this stage, there would normally be a clear favourite but I’ll give 1, 2, 4 and 5 a bit more thought and put 3 on the back burner.
