IMO funerals should be attended in the same way as weddings are, ie by close family and friends.
When I've been very upset at the loss of a close relative the last thing I want is to feel like there's an audience, with someone from 20 years ago 'paying their respects' or in fact having a nose.
It's like a badge of honour when people say 'oh the church was packed'. So what really??? It's who was there when they were alive that is far more important.
Agree with this.
I think it's nice to go to the funeral of a person you have known and cared about, (if you can,) as it is a sign of respect, and shows that you cared about that person. It should not be mandatory though, and people should not be made to feel bad if they don't wish to attend. There have been some pretty harsh comments on here, aimed at people who don't want to attend funerals, and these comments are well out of order.
What I have ZERO tolerance for, is people turning up at funerals of people they have had naff-all to do for 14-15 years or more. I have seen a few people turn up at a couple of funerals I have been to this past 3 years, (one family member and one neighbour,) who had had nothing to do with the 2 people who died since the early to mid 1990s. I thought what are they doing here? (A few other people thought that too.) They didn't bother with them when they were alive, why show they care now? 
I have known a few people come to funerals of people they have had nothing to do with for 25-30 years plus, ignore most people there, and then leave when they realise they're not getting anything in the will!
What also pisses me off is people attending funerals of people they don't even know and have never met! Several women who live 5-10 minutes walk from me, go to EVERY funeral at our local Church, and although it's a free country, (and they are allowed,) it baffles me.
How can you mourn someone you have never met? And how can you mourn someone you have had naff-all to do with for a quarter of a century? You obviously didn't give a shit about them when they were alive, so why pretend you care now they're dead?
And as for the 'they are showing respect for the family left' comments.... Why?
When close family members of mine died, the last thing I wanted was someone from the past who had had fuck-all to do with them (OR me) for 25 years, feigning interest, and smothering me with their 'competitive grieving,' and faux mourning.
I definitely don't want fake mourners and 'competitive grievers' at my funeral, and I don't care if there is only 20 people there. As the poster above said, it seems to be some badge of honour when the Church (or Crem hall) is 'packed to the rafters' and 300 people turn up. Yet I bet (in most cases,) 70% or more of those people had naff-all to do with that person (OR their family,) when they were alive.
