Ouch!
As a friend, it’s pretty standard to play pranks on your other friends. After all, it’s a sign of a close relationship! However, doing something like this “friend” did is certainly not such a nice idea. What was going through his mind when he chose to burn his friend’s leg?!

And leaving him with second-degree burns, too – ouch! That’s pretty painful! Unfortunately, the user didn’t specify who paid for the medical treatment, though I sincerely hope it was the friend. He deserves to, and that’s a fact! Hopefully, the scars will heal soon enough, both mentally and physically, from this.
