Mindee (nearly 11yrs) informed me last week that he doesn't like it at my house because it's boring. 
He's been coming here for 4 years and is treated like a member of the family. Over the last year or so, I've noticed a change in him - answering back, winding the younger ones up etc but I put it down to his age. My DS is the same age and sometimes displays similar behaviours. I have a zero tolerance on the back-chat and try to distract them all with an activity when the winding-up starts. It's never been so bad that I've had to contact his parents.
He walks to and from my home on his own and has done for quite some time so I never see either parent but have occasional contact via text if they need to change our normal plans.
He arrived this week and told me he has to 'stick it out' with me for another week or so and can stop coming at half term.
I've had no communication from either parent to inform me of this and feel really
that after all this time they didn't have the courtesy to phone me to discuss it.
I'm a bit torn between phoning/writing to his parents and pointing out the 4 weeks notice period to terminate contract or just letting him go at the end of next week and look forward to a peaceful last half term without him (makes me sound horrid, doesn't it
).
He'd be finishing at the end of the school year anyway as he moves up to secondary school.
Any advice?
