Mother shopping boredom?

My mother goes shopping today and when she leaves she saves my laptop and cell phone and locks it in her bedroom. What can I do then?

Or you go shopping

There are other things too.
Maybe you could do something for school, she probably means only good for you.

Offer her punches.

Why are you allowed to use the devices when they are at home and not when they are not at home? What is the reason for this?!

Wait until she comes back!

You can also get by safely without the laptop and computer. Read something, learn a little for school or watch TV now. You could also go shopping. If she has more to buy and haul, you'd be a big help to her and you'll also have something else to do instead of just sitting on the screen all the time.
