What is the idea? Like the child was waiting in front of a xerox photocopier?
The verb "a copia" is used for cheating (on a test). That was my interpretation after reading the sentence/
Maybe he hadn't finished copying what was on the board, so he stayed while the rest started their next activity.
What is the rôle of "ca" here? My first try was something with "as if."
Or, maybe the kid was in a drama class and wanted to copy an actor/actress reading their lines.
