Nobody likes to contemplate their eventual demise. Thus, individuals typically will not take the time to pre-plan their funeral arrangements. When death is sudden and not due to an illness, the remaining loved ones are left scrambling to make the appropriate arrangements and foot the expenses. However, it does not have to be this way. Just as you would take out a life insurance policy for yourself, you should also consider pre-planning your funeral too.
If you're religious, it can be very difficult to know what to say when attending a funeral with atheists and agnostics. There's a stark difference between what the two groups believe about death, and saying the wrong thing could upset the atheistic friends and family of the deceased. Comments like "he's with God now," for example, may feel well-intentioned on your part, but they're not appropriate to say to someone who does not believe in God.
