I'm thinking of dropping my friend on purpose after she preformed multiple back-flips in the gymnasium.
Why would that make you want to drop her?
because, I don't like her.
Why would you not like your friend? Don't drop her or else she will get hurt.
I got my reasons to drop her. She's disrespectful.
If she is disrespectful, then talk to her about it. Hurting her physically will not solve any problems.
