<human>: Can you condense the text into three sentences or less?

So my brother married his girlfriend in November last year without having a wedding or a proper proposal because he did not have enough money. His wife is very understanding about not having a wedding at the time. Fast forward until last month, when my brother got a better job and now wants to surprise his wife with a wedding proposal and to have an actual wedding in August. 

Things he wanted for the proposal is to have friends and family when he propose because he was sad that no one, except me, was there at the wedding procedures in City Hall. People have a busy life of their own so I will not fault them for not being there, and I was between jobs at the time so I had spare time.

So he plans to invite friends and family over to his house, hooray his owns a house now, and will have his dog bring his wife the ring and that is when he will propose. So he left me with the job of planning the evening with about 15 people at 8:00 PM on a Friday, May 30... If it helps, I live in Southern California.

I never heard of a proposal party before and have no idea what to plan for the party since he wants it to be romantic and yet have friends and family over... 

So
<bot>: is my brother is proposing to his wife. What goes on in a proposal party if there is such a thing and what can I plan for that is romantic and appropriate for the occasion?
