I'm definitely having a direct cremation. IDGAF if it's 'just body disposal.' What do you think a cremation is when there IS a funeral? That it's stuffed and people take it home and display it in the dining room?!
I don't want a funeral, and both my (adult) DC have said they are more than happy for me to not have one. DH is the same. He wants a direct cremation too. Can't see the point of a funeral, I don't like them, I don't like going to them, and I think a simple alternative is an excellent idea.
Two thirds of the people turning up at funerals are often people who've had fuck-all to do with the person who is dead for the past 20+ years anyway. I can't stand faux mourning from people who probably didn't even know the eye colour of the deceased, or their middle name, and who haven't seen them since the last century! You even get people turning up who never met them!
I went to a funeral of a man who died very suddenly in June, (a neighbour.) We saw him most days and he was friendly and chatty. Around 100 people came to his funeral at the town crematorium. Around 60 of them I've never seen in my life. (And I had known this man since 2010.) Before the funeral, there were crowds of men laughing and joking before the funeral, and saying 'y'all right mate, not seen you in a couple of months, how's tricks?!' and slapping each other on the back. Hooting and jeering like hooligans.
It was a fucking funeral, and they were acting like it was a school reunion, or a party, or a wedding 'night do.' Pissed as farts as the wake at the local social club, within an hour of getting there. So fucking disrespectful. The close family of the deceased gentlemen left the wake after an hour, and all these men kept partying into the evening. 
Like hell is that happening when I die! There was no celebration of the man's life, it was just a piss up, with a load of free food!
