Am I being reasonable here to be very disappointed in DS14 today, here's the back story
DS14 asked me this morning to fill his water bottle up, and put it into his kit bag for him, as he was off out to play football at a mates house. On opening his bag, I saw a load of fruit which he'd purchased.
I asked him where he'd got it all from, and what he was planning to do with it - he said they were gonna use it to play football with, and to hang in the nets and take shots / aim at, and practise kickups with - DS played this once before at the beginning of the year, and asked to play it again a few months ago which I told him off for, and told him to find another activity.
He said he'd purchased all the fruit yesterday (spend £20 on it) after school, and didn't tell me cause he knew i'd stop him from doing it again, he said it was his time and money, and he could do what he wanted, and that he enjoyed doing it (and I was being a kill joy) and then stormed off, taking his bag with him
Am I being reasonable for being overly disappointed in ds here?
