I would try being extra nice to them....say how lovely it is to see parents and grandparents playing outside with their children instead of being stuck in front of a screen.Try not to let the situation wind you up.. there will always be something to iritate us and if this continues you will be the one compelled to leave........dont give them the satisfaction! My Auntie and Uncle had a similar thing with noisy neighbours who became more noisy the more they complained and in the end my relatives left a perfect flat with a lovely big balcony for something which doesnt them at all.Just ask them to be a bit careful near the cars.Grit you teeth and smile at them maybe buy them a new football for xmas......it might work
I can't believe my car insurance has risen by that much!
