15 yr old dd - 1.5 hours late

[felttippens]

She's due in by ten and Is 1.5 hrs (and counting)

I'm so stressed and mad heard nothing from her but a message via a friend

What is suitable punishment ?

Thanks everyone for Input

Today I've spoken to teacher
Bought 'get out of my life but first take me and Alex to town'

Dd has tidied room, done dishes and homework

Do you know whether something did happen last night, or is she just chancing her luck?

Don't think anything happened last night but seems she is getting fried at school for girls in year above
