Imagine if I started a story with something like: The male students stared at Mary as she exited through the school gate. Mary loved having their attention. Is this considered bad, because the first sentence starts with the male students, while the second revolves around Mary? Would this be considered a sudden perspective change? I haven't explored the male students' thoughts, though. So, if I started a story like this, could I still say that the tale unfolds from Mary's perspective? Thank you.
