My daughter had a slagging match with another girl via text which naturally the other girls mother informed me of.
I made her read out loud the sentence she had sent to the girl.
She was horrified. Said she couldn't say those words (there was swearing in it).
It finally dawned after a conversation that by typing them she HAD said them even though she hasn't physically uttered them out loud.
It's a tough lesson that they have to learn when they realise stuff sent by text/social media is just as real & damaging as the spoken word and once it's out there they can't retract or delete it.
In her defence she was sticking up for s friend. All her swears were in the right place and the other girl is a notorious bully, has been for years.
She was however outplayed & out manoeuvred as the other girl hadn't screen grabbed her initial messages OR responses to DDs one and only message. DD was still suitably punished, although I doubt very much other girl was, and fingers crossed lesson learnt.
It's a tough environment they're growing up in with no escape thanks to mobile devices/social media. She's been told she doesn't have to be instantly available to everyone and it's lessened the stress of it all.
And sorry but against most other posters she knows that DH and I are able to check her social media sites/phone at any time. Less invasion of privacy and more about protection. At 12 she's still a child and we would monitor what she sees on TV etc so
same goes with FB/Instagram etc
We don't tend to however the deal is it's our phone, we pay for it (she goes to school some distance away so needs a phone) and if we ask to see it we can.
Good luck with that conversation OP. My DD used the word bitch (in a quote back of what other girl said) but it was still enough for me to come down on her like a tonne of bricks.
