Congratulation To Marriage What Happens Straight After A Marriage Proposal?

What happens straight after a marriage proposal? - congratulation to marriage

When he proposed to her partner (or) proposed and accepted, hold the duration of the shock, her eyes open? If you are a spectator, then I ask myself uncomfortable after a certain time? I can imagine it is so important, and nobody knows when the compliments stop. Anyway, any thoughts / stories would be a good thing:) Thanks
