Today is my lovely friend's birthday

Today is my lovely friend's birthday.
I would like to invite him to celebrate his birthday.
I wrote an sms .. and suprising that he refuse my invitation.
Why ?? I don't know.

If friends refuse your invitation eventhough by respectively, how do you feel ?
Of course, you will disappointed, won't you ?
But .. I try to understand eventhough I don't know the reason.

It's ok my lovely friend.
I hope you could enjoy your birthday.
I hope you are happy today.
I'll always love you.
Have a nice birthday.
