Is it wrong that I'm thinking of creeping out this girl at work?
Why on earth would you want to do that?
I think she's pretty and she's also nice to me
You shouldn't be creepy at work. If she sees you being creepy she will report you to HR and you will be fired.
I think it'll be fine. If I get caught, I'll go on a full blown tantrum.
You should behave more professionally at work. It's wrong to make a co-worker feel uncomfortable.
