Earlier today went into the local town for some shopping and saw a Y7 that I teach and said hello, asking if she was with her parents (get along well with the parents) and she said she was with her older sister (who I taught for 2+ years), and no big issue. I tried to say hello to the older sister but she walked away. Felt really uncomfortable and bought what I needed and as I was paying, joked about the rudeness of the students and was informed that there was past evidence of theft. Am gutted that a student who I taught until last June, teach her younger sister currently and have a good relationship with the parents, was rude when we saw each in the local community (with my response always and only a 'hi'). And I'm actually taking her on an overseas trip in a few weeks! Part of me wants to tell the student how rude I thought she was but am wondering if her response was more 'oh, no...it's a teacher - run!' and why I might be oversensitive, I was very mindful of them being in the shop and what embarrassment a teacher might cause but a little upset that a student was so rude. Given that I am taking her along over half-term on an overseas trip, would you say something along the lines that you were confused by their behaviour, etc? Just curious and thanks.
