• You are so beautiful.
• You crack me up.
• You're really smart and really talented.
• I came close to losing you once.
• We've known each other since we were really little.
• You're the kind of person I could see myself falling in love with.
• You were my first crush.
• Off and on I've wondered if I've had a crush on you again.
• I love your family.
• You have great taste in music, clothes... everything.

and that, my friend, is some of why love you.
