Why do I feel like I relate to the kids more than adults? Is that a bad thing?

I work at an autism school and I can relate to those kids because I’m in the autism spectrum myself. When I’m around the adults I feel alone. Also when is adults are around, they talk about nasty things, curse and talk about naughty things and sex but not all the time. Mostly adult things. I get uncomfortable with adult talk but my older siblings said I SHOULD be hearing these kind of things and I’m old enough to hear adult things now and they won’t mince their words anymore around me since I’m “old enough”. I’m 19. When kids have a meltdown people makes it not a big deal, but if it’s an adult, they don’t feel sorry for them and expect autistic adults to get over themselves and stop the drama.
Kids don’t judge you, they just play and have fun all day. So sweet and say the cutest things, even though their blunt.
