Marriage proposal is private, I would not want anyone else was there. The place and the day is not so important. The main thing is not to get married because my mother said that at her age she had children (like in my case) and is not decent to be happy / enjoy the life :) when all my friends have 3 children and more. Mom says: "do not tell me where you spent the holidays, do not smile, do not say do what you want, do not say that you sleep till noon, they want you to embed on your the face satisfied!!!"
