Why do populace find their own farts smell pleasant?

I farted in the vehicle yesterday and it was a really strong odour, I be enjoying the gash wrenching gases when my friend farted too and it could no longer delight in mine... Why is that? Are there chemicals or something within our farts that our bodies recognise and know to enjoy? Thanks!Why do populace find their own farts smell pleasant?
I suggest it's pride in what we can do next to our intestines. Same as taking a crap and texting the pic to your friend on a cell phone...
They do?
I live this question lol..I hold no idea
