How would you show respect to a person who is not respecting you?

In our company, I am working as an ordinary staff under the supervision of so many bosses. In my position, I dont mind working under pressure and being instructed by too many people. I dont mind if they ask me to do it urgently. What matters to me is to have at least a little respect from my colleague. But, unfortunately, I am not getting it. It goes like this, I am about to print one letter when other task was instructed to me, I need to left the letter for a while on my table to do that task. Then, when I came back after doing the other thing, the letter which I left on my table subject for printing, suddenly disappear. What I did, I have tried to look for it thoroughly for about half an hour (likely 30 minutes). And trying to think, where I possibly put the letter. Since that letter is my responsibility, I am quite afraid if the letter will be lost. However, to my surprise, I saw it in the hand of one of my colleague. Wherein he took it away from my table without informing me. And after a minute, he return it to my in-tray. The point which I am trying to figure out here is, I dont mind if they want the letter be given back to them or if they want to do some modification. All I want here is just to inform me at least and a little respect, hence, if the letter had been lost, for sure, they will blame me for that. Hence, if they keep a little respect to me, at least, they will somehow inform me that they will going to take away the letter for a while.
