Write the next sentence in the following story.

How to tell a girl she is pretty
Pick the right spot.
Your compliment might not be welcome if the setting is wrong. Inside the office, at a professional meeting, in the classroom, and even out to lunch with colleagues are inappropriate situations to tell a girl that she is pretty.
Doing so in these circumstances will put the girl on the spot and could embarrass her, which is not what you want to do. A compliment could also seen as inappropriate if you are on strictly professional terms, either by her or by co-workers and friends.
