DS is 13 - whilst I haven't ever explicitly said that I would randomly check his phone, he knows that I could do as I know his code and I do check his messages periodically.
Anyway, he went out yesterday with some friends to an indoor football place. I dropped him off and he walked back a couple of hours later.
I checked his phone this morning and there was a message from one of his friends saying 'was your mum mad'? And DS response of 'I haven't told her'.
Part of me wants to ask him as I'm curious about what he did that I would be mad about but the other part thinks whatever it was probably can't be too major as he came home on time with some money left and is generally responsible. If he went somewhere else, I would probably be annoyed that he didn't tell me but not overly bothered (at his age, I was roaming all over with no way of letting my parents know!)
If I challenge him, he'll clearly clamp down on what he puts on his phone which I don't want, he doesn't actually go out with his friends that often so my instinct is to let this go as it's probably something and nothing. But I am annoyed that he is being deceitful but, again, I'm sure there was lots I did that I didn't tell my parents so not unusual for a teen!
Any advice on how to handle it?
