I left a puddle when I peed my pants and then I let someone else got blamed for it.
That wasn't right to do to someone. How did that even happen?
I blamed my brother for peeing on my pants.
You should tell the truth even if it will bring embarrassment. There is no good thing that comes out from lying.
I disagree, my parents are proud of me and my brother is always bad. I don't want them to stop being proud of me.
You need to admit to what you've done by blaming this on your brother. If the consequences of that mean you're parents aren't as proud of you anymore then that's really what you deserve. I'm sure you'll make them proud again by starting to be honest.
