It is annoying for someone to assume that because one is autistic they shod be treated like a toddler. I'm moderately autistic (is that a thing?) and frequently experience this, especially if I'm hardcore stimming (rocking back and forth, running fingers along an object I like with a toy in my mouth). They forget that like other adults, I too have adult interests like history and architecture.
