At 9 you are a bit to young to be wanting frednship with a 13 year old.
He's mean
You know who likes biscuits?, YOUR MOMMA
If you want to know anything about females just ask them or ask their friends.
Talk to his close friends if he likes you and if they can keep your secret.
keep a look out & see if he's flirting with you!
Tell her you like her...you never know maybe she likes you too. =)
