I just have to get this out!

I understand totally! We also have friends who come for dinner and never even bring anything, eat out food then leave without even offering to tidy up.

I do understand also why ppl think if you asked what to bring, they said something and end of story and usually it would be in most other situations.
But you know these people and by the sounds you are bringing the dinner to their party.
Do you know what they are making. Maybe you could call them back and ask, if I am bringing the chicken what are we going to have with it? I am not sure but as I said we have Friends like that too so totally get how annoying that would be!

Oops, lol! Next time don't ask if you don't want to bring anything. And you could have also have said no. I would have just said 'sorry, don't have time to organise that but I can bring ......' etc
