Rusan has to pay for my laptop damage
Rusan sat on my laptop which was very rude considering many chairs were open. When I asked him to get up he said "it's okay I moved your laptop to the back of the chair" and he assured me it was fine so I was like ok whatever a few minutes later I realized I was still uncomfortable about it and I was like get off my laptop right now and he was like ok and I snatched my poor baby (my laptop) it's not okay he sat on something that expensive without any thought I even put my laptop on a chair in the corner so nothing would happen to it this is not okay or fair I got this laptop as a birthday present and I need it for school if I don't have it I will be forced to be a high school drop out how could he jeopardize my whole future like that?? It's really not okay he has to own up to his careless actions and pay for the damage or buy me a new one PERIOD
