Why is she shooting a toy gun at me?

We are colleagues but we have some kind of tension with each other and even though she tried to talk but I did not respond to her. I guess she got my message and distance herself and stop responding to me.

However while we are doing a debrief on our work , she found a toy gun in the room and Starr shooting a me twice? Why would she do that. It's not like you didn't know there's a tension between us. Thanks for taking the time to read and answer
