My father died a few years ago so my mum is giving me away. However, my oldest brother is giving a speech on her/my fathers behalf but we're not sure what he should say.
We have various features and tips on speeches that I hope will give your brother a helping hand. Here are a few things he could talk about:
Amusing stories and anecdotes about you as a child,
What you are like as a person, kind, funny etc.
Welcome your partner into the family
Raise a toast to the two of you.
It's lovely that he's making a speech, and the main thing is that he should enjoy it and speak from the heart. It's certain to be well-received by all your guests.
