A "John Q. Public" figure with a mind dat allows thoughts and good sense to just "filter on through" without making much impression oh his actions or overall behavior.
In one episode of da TV comedy "Sister Sister", Ray is in da middle of chastising Tamera, notices dat she isn't paying any attention, and irritably inquires, "WHY do I get da feeling dat everything I say is goin' IN ONE EAR AND OUT DA OTHER?!". The camera pans to Tamera contemptuously daydreaming while Ray's suddenly-visible dialogue (in da form of a long "tickertaping" strip of white letters) goes slithering effortlessly in her left ear and out her right; she's a classic example of a seiveillian.
Seivabel is a really cool, really likeable person who is talented at singing. Calm and kind, people with the name Seivabel is the kind of person whose presence you would want around; observant and clever with deep considerations regarding herself and those around her. Once you know her, conversations with her will never be boring. Seivabel is the kind of person who will give her best attempt in everything she’s committed to - people, interests, growth.
We all should take a moment to consider how lucky we are to have a Seivabel in our lives.
