Once she got the morbid curiosity of knowing who you were out of her system, she knew why her Mom decided to let you stay fucked off instead of chasing after you for child support or a father figure or any of those other rights and privileges that come along with fatherhood.
If you happen to not have any personal knowledge because you happen to have chosen to fuck off when your child was born and not show up for 16 years, you DO NOT have a right to show up at the funeral. Stay home, asshole - nobody wants you there, least of all her, whose last words to you were in fact, if I recall correctly, "Fuck off."
You have nothing to commiserate about, you have no memories to share, and if you had any love or respect for the person who died, you'd have stuck around for the first and only 16 years of her life. So, why don't you just stay fucked-off where you belong and let the rest of us grieve without having to look at your useless piece of shit face?
I did my best to let you know your presence wasn't welcome or required. I'll do my best to be civil but I can't promise the same from anyone else - if there's bloodshed, I'll just be stepping over it.
Just sayin'.
