Is it wrong that I didn't talk to the old man but I knew he was there waving at me?
Did you say something to him before?
I told him I come to the library not to talk to strangers.
You don't have to talk to people who you don't know. Like you said, you're there for the library. People should respect that.
I would just rather him leave. I need to get things done.
I wouldn't think about it too much. You were busy and didn't need to talk to him at the time.
