I called her over to me and gave her a hug to place the sticky note on her back that said nerd.
That's mean. Where were you when you did that?
The mall. I wanted to embarrass her in front of as many people as possible.
You should not play pranks on people. Making fun of her was mean and hurtful.
But she is a boring nerd.
It doesn't mean you are allowed to prank people like this and hurt their feelings. I doubt she is a nerd, and is actually a wonderful person! Try getting to know her a little better to see what she is really like.
