It’s a good idea to arrive at the funeral early so you have time to talk to the funeral director and other pallbearers. You’ll agree things like:
How to carry the coffin (on shoulders, by the handles or on a bier)
Where you will stand when you’re carrying the coffin
The route you’ll walk along
You’ll also want to practise walking along your route so you know if there are any steps or other things to be careful of.
