Have been unconsciously avoiding large crowds

So I was in sixth form the other day and to get to the cafeteria you can either go two routes 1) go through large crowds of students outside or 2) go through the corridors inside where no one walks through

And I was walking through the corridor and realised to myself "wait why don't I ever go through the large crowds?" So I'm just wondering if this is just me overreacting or it's me now unconsciously trying to avoid crowds.
