It’s a part of a book or film which covers a single event, and predominantly with a set group of characters.
It could also mean it might relate to a particular genre that you like, as in,
I’m part of the jazz scene or the symphonic scene, though I think it had a more sinister context back in the late 60s early 70s.
A scene could also be a landscape (especially in art)
Then, of course, the last thing you want is a child to make a scene in front of others, in a display of temper, or bad manners
This is not to be confused with seen, as in, you should be seen and not heard, an oft used expression by a parent.
You could be seen, especially in places where you were not meant to be, or, conversely, make sure you are seen by the ‘right’ people in the ‘right’ places
Have you seen my dictionary, it’s quite large and heavy
I have seen his bad qualities
I have seen better days, though at the moment I can’t remember when
I have seen them all, sometimes seemingly impossible, but it is generated by exasperation, and generally more like I’ve seen everything now!
