Check All Of The Above

I'm a day dreamer, My heads in the clouds, But when I fall down, Won't you be my solid ground, I tend to block people out, I'm hard to reach, So when I put up another wall, Just break them all, I find it hard to laugh, I'm not easy to crack, But when you can tell it's been awhile, Do anything to make me smile, Many have tried, Many have failed, I'm hard to love, Becasue you have to do all of the above,
