My mother threw my laptop out of the window in anger yesterday.
Can I display it now?
Ps: That's no joke, that's what she really did
Pps: I paid for the laptop
Sure you can. If it was your property, because of the property crime. In addition (whether it was your property or just in your possession) because of the endangerment of life and limb of the passers-by who might have killed the laptop.
Honestly, what's up with you, that your mother throws the laptop out of the window? It must have happened so much that your mother is so freaking out. Your idea of showing your own mother shows that there's something wrong with you. What do you think happened after you have your own mother displayed? You still live with her. Where should this war end and who believe you are sitting on the longer lever.
Of course, you can show your mother, but you risk losing your relationship even more. See if you can find someone within your family who can mediate between you and your mother. You should also think about why it came to the scandal, maybe not only your mother, but also you have made mistakes from which you two can only learn.
If no agreement is in sight, contact a counseling center, e.g. Here https://jugend.bke-beratung.de/views/home/index.html or to the youth welfare office.
