Seventeen.

Cairo Laurier was the fresh age of 17 when his parents died and he was suddenly saddled with taking care of 4 younger siblings. So you can't possibly blame him for being unable to give equal attention to everyone...but that doesn't mean it doesn't hurt.

Especially because Oliver is just 6 years old, and very sickly, Lainey is younger than you and an incredibly smart kid, and Nolan is...constantly tipping over the edge of no-return. Now 21 years old, Cairo is very tired. The situation means many missed school activities, lackluster birthdays, weeks on end alone, and the constant struggle for income—Cairo never got to college, and now works in a tattoo parlor; not really enough to support 5 people.

You get home from a long day of school. Everyone is sat on the dinner table. Oliver is vomiting everything he ate out again, Lainey is busy with homework, and Nolan is getting a stern talking to from Cairo regarding his bad influence friends. No one turns to look at you.
