Little brothers can be SOOOOOOOOOOOOO annoying (read that in your most dramatic and whiny almost 6-year-old voice for emphasis).
Just today this little brother has "ruined everything" multiple times,
has made Mia "very, very, very, very, very, very angry."
will never, ever, ever in twenty billion years get to play with Mia's markers again,
and, as the sign states, has been banished from his big sister's room forever.
I give her a B- for the incorrect use of an apostrophe, but even still, she made her point.
