Am quite prepared to be told IABU. (have NC as I think DD and DH lurk on MN occasionally
)
Bit of background: we live in a small town, DD goes to college here, it takes 10-15 minutes to walk there. She finishes at 3pm but stays until 5pm once a week for one of her classes, she and 3 other students are working on a project together. Tonight isn't one of the 'late' nights. DD does have form for setting her phone to 'silent' and not noticing texts. She doesn't stay out late, go partying, or go out with friends without needing a lift letting us know (small town, no friends nearby).
9:30 this morning I got a text, she asked if she and the other students could come here after school, they'd pick up frozen pizza on the way. I replied yes that's fine. (the shop where they'd get the pizza is on the way home).
At 4pm I figured they were in fact staying late, I sent her a text asking what time to expect them all. At 5pm I sent another text, asking if she was on her way, so I could put the oven on. At 5:30 I re-sent it. No reply to any of them. At 5:45 I started to get a bit worried. Even going to the shop and faffing about with friends, I'd expect her to be home before then.
At 6pm I called her friend who I know well and asked if she could send me mobile numbers of any of the other students (I do know the other students to chat to, I'm not a faceless 'someone's mum'). I texted two of the other students asking them to get DD to call me.
DD called a few minutes later. They'd been working on their project, all plans changed, they were now going to stay at college until 8:30pm to finish it.
I grew up in London so I think my 'warning radar' is a bit sensitive. A 17yo shouldn't have to account for every second of their time, and I don't want to be the dreaded overprotective mother. But AIBU to have been worried and did I over-react by texting her friends? If I hadn't heard anything at all until 8:30 I'd have been panicking.
