Your experiences with funerals has me laughing and smiling. I can just picture it all! The worst thing that happened for me at a funeral is that I started laughing uncontrollably, it was my grandfather's funeral and he had done some pretty bad things to me.Before my family gave up on funerals and moved over to the "let's incinerate him and have a big party afterwards" school of thought, we had more than one dysfunctional funeral.
There was the great-uncle's second wife that arranged for someone to come to the cemetery right after the funeral and buy back all the flowers from her. That didn't go over very well.
There was the funeral where a mentally-ill niece ran down the aisle of the funeral home and dived head-first into the coffin yelling, "______, _______, don't go! I'm coming with you!"
There was a great-aunt's funeral where a portion of the family was screaming accusations at each other in the parking lot outside the funeral home. Before AND after the funeral, no less.
But the best one was my father's cousin's funeral. "Bud" had been messing around with the wife of a jealous man and had received a fatal dose of lead as a result. Of course, the family story was that it was just a case of mistaken identity. Sure. Anyway, the funeral is about to start in a small country church. The widow, "Beulah" (Big Beulah, as she was known in the family for very good cause), had just been seated when the girlfriend slithers in, dressed in black from head to toe, heavily veiled. She sits down halfway down the church and starts in. "Oh, Bud, you were too good for this world! <SOB, SOB, SNIFF SNIFF SNIFF> Bud, what am I going to do without you? <SOB, SOB, SNIFF, SNIFF, SNIFF> Oh, Bud, why did you have to leave us. < More sobbing and sniffing>"
Beulah gets up, steps out into the aisle, arranges her veil back, walks down the aisle and snatches the sobbing girlfriend out of the pew and proceeds to mop the floor with her. I was not quite six, but I can remember the scene like I was looking at it on Facebook. All I could see was Beulah's huge, yellowed-girdled-covered butt (her dress had ridden up) as she kneeled on the girlfriend and banged her head on the floor. My mother was trying to get me to get down from the pew but no way was I going to miss THAT. The men get Beulah off the girlfriend, hustle the girlfriend out, and get Beulah brushed off, properly covered and back in her pew. The funeral proceeds. Luckily there were no more fireworks at the gravesite.
See why I don't like "funerals"?
Back to the OP. I would go to the funeral if I wanted to pay my respects but agree with the others not to do the tid for tad thing.
