I also hate when somebody takes my things and more than all damage them. We have two children and it is an actual problem for us. Once, my son found my cape and started to "draw" with it on the window. Fortunately, with cape did not break and it is all right, but the panoramic window in our living room we had to resurface. To tell the truth, firstly I thought that we will have to replace it with a new one. But our friend advised us ***** that can repair and actively restore large tempered glass panels. Indeed, it was the best solution, because it was a cold time of the year and it really helped to save a lot of money.
