I'm a student teacher (f23) in year 2 of my degree, why do I get the sense that other qualified teachers in my grade don't respect me?

For context, I'm studying a bachelor's of education in foundation phase teaching. I'm currently doing my teaching experience at a school. I noticed that when I was in the middle of doing a lesson, other teachers would barge in and walk past me and go straight to my mentor teacher to gossip about something or relay a message, instead of waiting till I was done. Now I understand if it was of urgency, but it hardly ever is and they never say excuse me or anything like that. Am I crazy for being upset about this, cause it happened more than once an dim wondering if I should speak up
