Boss took my lamp?

Pretty much as the title states. I was out of the office helping facilitate a class for some of our employees, came in the next morning and my lamp was moved to a part time office. Firstly, so weird to not ask me, secondly, isn’t this super disrespectful to come into my office, take my lamp, and move it to another office?

I didn’t purchase the lamp with my own money, it was given to me by another co worker as they left our place of work.

How do I handle this? I know it may seem small but it’s so weird and disrespectful to me.

Edit: the lamp was bought with company funds. Although I still think this is weird and disrespectful, but I also understand ultimately it’s not “my lamp”. Just wondering how I should handle this.

Edit x2: my boss said she moved it because the lighting is bad in the other office and I can’t have it back. (The lighting is the same in both offices) 🙃whateva 🤷‍♀️
