Lyrics of Happy birthday

Hey you, i know i'm in the wrong
Time flies when you're having fun
You wake up and half the year is gone
You're twenty-one

I guess you wanna know
Why i'm on the phone
It's been a day or so
I know it's kinda late
But happy birthday

I know you hate me
Well, i miss you too
I know it's kinda late
But happy birthday

So hard when you're far away
It's lame but i forgot the date
I won't make the same mistake
I'm so to blame

So now you know
Don't hang up the phone
I wish i was at home
I know it's way too late
But happy birthday

I know you hate me
Well, i'll miss you too
I know it's kinda late
But happy birthday

It's stuck now, i don't care
No, i make it up to you
If i could i'd be there

Well, i miss you too
I know it's kinda late
But happy birthday

I know you hate me
Well, i miss you to
I know it's kinda late
But happy birthday
To you
