When we say "A stole the toy", it implies the toy belonged to someone else before.
Similarly, when we say "A stole the spotlight", does it imply the spotlight belonged to someone else before?
Situation 1, say, Mary was standing in front of a lot of students bragging about her success when suddenly, Jen, out of nowhere, sang loudly to get attention from the students. We can say "Jen stole the spotlight".
Situation 2, all the students were eating in a cafeteria when Jen, out of nowhere, sang loudly to get attention from the students. Do we say "Jen stole the spotlight"?
