Bleeding behind my ear

I was trimming the fur clumped up on Mandu's ear with scissors and accidentally cut a bit behind its ear, causing it to bleed. I freaked out and was like, 'What do I do?'... But Jo-Mandu is totally fine, laughing and acting wild as usual... Is this for real? 🤔🤔🤔🤔 My reaction when I accidentally cut it: 😰😰😰😰😰😱😱😱😱😱 Jo-Mandu's reaction: First: 🙁 Now: 😆😆😙😙 Is our Mandu just a 'my way' kind of personality? 🤔🤔 I'll just keep an eye on it, and if it seems to be in pain, I'll take it to the vet, I guess.
