Honestly, she seems to be on a short fuse and my antics probably didn't help, I'm not sure about the context but I know what it's like to have a bad day. I decided to just let this go, she may have been rude but it was entertaining for me. "It's fine, we all have bad days." I still keep my words simple and tone level as I brush it off and nod to them both before going back to my book.
