how can i?

Remember the day when you first gave me your number?
I was so scared to call you, After hearing my voice..
I thought you'd run.. But you didn't..

Remember the time when your dad first found out about huge ph bills?
He scared the shit out of you..
I thought you'd ask me not to call you ever.. But you didn't..

Remember the day we first met?
I was so nervous..i just couldn't talk..
I thought you'd think I'm a big bore.. But you didn't..

Remember the day when we had our first fight?
You were so mad at me that day..
I thought you'd hit me.. But you didn't..

Remember the day when I acted all jealous?
I was so angry that you were talking about some other guy..
I thought you'd kill me.. But you didn't..

And remember the time when I'd call you in the middle of the night?
Just so I can take out all my frustration..
I thought you'd simply walk away..But you didn't..

Yes there are lot of things you didn't do,
But you put up with me, stayed there and protected me..

And I want to makeup for all the things you did..
I just don't know how can i?
