I'm planning to put tranquilizer into chocolate for a girl I want to date.
Why to you want to feed this girl tranquilized chocolate?
Because she's too good for me. I want her to get close to me and I want to get rid of all of my love anxiety
Even though you feel anxiety and want to get close to this girl, you should not put tranquilizer in her chocolate so you can get closer to her. It is wrong to spike food and feed it to other people.
What's wrong with a bit of seduction?!
This isn't seduction, it's assault. If you want to get to know her, you should do it the right way - by talking to her and showing her who you are. Tranquilizing a person is a crime and you could seriously hurt her if you're not careful.
