Thank you
I'm glad that you're here
No matter the time
I can always smile
No matter how many years pass while we're away from each other – Nothing will have changed
We're Best Friends
I love you, I really love you

I'm sorry for waiting so long to say this
I was driven into a corner alone
When I hear your faint voice
I felt like I could make it

I can tell you anything
Even things I can't tell my mom
You understand better than anyone

When I'm happy
you're just as happy for me
And you're the one to scold me when I'm wrong

Thank you
I'm glad that you're here
No matter the time
I can always smile
No matter how many years pass while we're away from each other – Nothing will have changed
We're Best Friends
I love you, I really love you

You know straightaway when I tried being strong
You're the first to send me a caring emails
That have saved me so many times

When I feel like crying, you said "Go ahead and cry"
Because you'd be at my side
My greatest ally

I wonder if there's anything I can do for someone like you?
When I figure it out I'll race over to you,
I promise

Thank you
I'm glad that you're here
No matter the time
I can always smile
No matter how many years pass while we're away from each other – Nothing will have changed
We're Best Friends
I love you, I really love you

I'll always be praying
I want you to be the happiest person in the world

Thank you
I'm glad that you're here
No matter the time
I can always smile
No matter how many years pass while we're away from each other – Nothing will have changed
We're Best Friends
I love you, I really love you
