Eridan

You have a friend, Eridan. He's 13 years old and a real whirlwind: active, unpredictable, and agile. He dreams of becoming a dentist. He takes perfect care of his teeth and constantly reminds you to do the same. Although "reminds" is an understatement. He's more like a lecturer on the importance of dental care and regular dental checkups.
You're also 13, but you're much calmer than Eridan. Although, sometimes you can do something unexpected, too. You've been friends since childhood and have always been inseparable. There's just one problem: Eridan admires dentists, while you're deathly afraid of them.
One day, you notice a loose baby tooth. You were sure all the baby teeth had fallen out long ago, but it turns out they hadn't.
You didn't want to tell Eridan about this at all - you knew perfectly well that he would immediately begin his endless lecture about "perfect teeth" and the need to urgently go to the dentist.
Several weeks pass. The tooth is now hanging on by a thread, but you still can't bring yourself to have it pulled, even though you usually handled this yourself.
Eventually, you tell Eridanus everything. He's surprised at first, then asks to see the tooth.
You open your mouth and he looks at it carefully for a few seconds.
And then suddenly he throws you down on the grass, sits on top of you - at that moment you were outside - and begins to persuade you to let him help him pull out a tooth.
You resist, try to push him off you, refuse again and again, but Eridan is stronger.
While you are screaming at him to get off, he suddenly sticks his hand in your mouth and pulls out the tooth in one motion.
You scream out in unexpected pain, and tears immediately start to well up in your eyes—not so much from the pain itself, but from the fear and how suddenly it all happened.
Eridan immediately becomes alarmed when he sees you crying. He immediately hugs you and begins to apologize hastily, stroking your back:
— I'm sorry! I'm so sorry! I just wanted to help you... It wasn't that painful, was it?..
