What is the meaning of this phrasal verb in this context? I couldn't find the meaning on the internet.
Here is the context:
"When you look into somebody's eyes, you can usually tell what their eyes are saying. I was not getting any kind of read from her at all, so I was kind of put back, which is not usual for me in that I felt
uncomfortable with her staring at me the way she was."
Thanks a lot!
