An alien who comes to earth with the assumption that humans are like pets so they walk around squealing at all the cute humans and walks up to one holding a cookie up to their face.
“Whooo wants a cookie! Does the cute little human want a human treat!”
“Uh, I just ate sorry…”
“-gasp- you can talk! Oh you’re so cute I love you adorable humans!”
“I have to go I kinda have a job over there.”
