When I was at primary school, it was very common for all of the students to buy their class teacher (and sometimes teachers from other classes who they liked) presents like flowers or chocolates and to give them cards. This was the case even for the students who were really badly behaved at class so it wasn’t some sort of “teacher’s pet” kind of thing. Additionally, it was common for all of the students in the class to give each other Christmas cards at Christmas and to the teacher (even if they didn’t celebrate Christmas).
Note: I went to school in a working-class area and this is only like 15 years ago (and I mention that because you might assume that there are some class differences with middle-class schools/private schools more likely to do that but that wasn’t my experience).
But, this didn’t continue at secondary school or sixth form with gifts only given to teachers by some students and no Christmas cards.
Is this common in your experience for yourself or your children - even to this day? What explains this?
