Breathe

Is it ignorant to go though someone's belongings and throw things away that appear to be empty? To me, this bottle is not empty and still has about 10 uses left of it, not to mention it's kind of expensive. Always nice to come home and find 5 of your things in the trash. I don't care if it's almost empty or not, it's mine, I haven't bought a replacement yet and clearly if it was empty I would have thrown it away.
