Having to force kids to write about everything As a child, I remember a certain realisation that school trips were always followed by having to write about them! My mum was big on keeping diaries as well.
I give tuition in pupils' homes, which has different issues, here are some of mine:
When the pupil is only five minutes out of bed when I arrive.
When both the parent and the pupil are hopeless with appointments. Sometimes the only way I can get anywhere with them is to text them before every lesson; even charging them for missed appointments doesn't work in some cases, they just pay up!
When they haven't had breakfast (or any meal since breakfast, for afternoon lessons).
Parents who have LOUD conversations nearby. (I don't mind cats who sit on my lap though!)
Pupils who are so good at mental arithmetic (better than I am), and think that because of this they don't have to show any working.
Parents or grandparents who say nasty things to their children in front of me. I once stopped giving a pupil lessons because I couldn't put up with this.
