It is beyond me

My Uncle Stan died on Friday. He was buried yesterday. It's been a while since I've gone to a funeral for somebody I actually knew well, and throughout everything that happened that day, I truly don't feel like there was closure. I felt like there was a lot of shit going on that I just couldn't wrap my head around.
The main one is a matter of respect, or lackthereof.
While driving behind the hearse on the way to the church (my dad was in the funeral procession, so we were marked as such) people were cutting us and the rest of the procession off, running through streets, not giving the hearse a break to pull through, cutting their way INTO the procession, it was absolutely ridiculous. Call me old fashioned, but when I see a hearse driving down the street followed by 5 cars marked 'FUNERAL', I don't cut into the line then start honking my horn 'cause traffic's slowed down. I know there are lots of people who aren't religious, and don't respect religion, and I have no problem with that whatsoever, but when it comes to something like this, it goes beyond religion. It's respect for those who have passed, and those who are mourning.
I just plain straight up don't get it.

Either way, Stan, you were a huge influence on me. You taught me many things about music and morals as a child that undoubtedly shaped me to be the way I am. I feel absolutely honored to say you were a relation to me, and I'll love you from this day forward as I always have.
Rest in Peace, and don't have too much fun without us.
