Chill out.
When you have spent 24 hours cramped up in a plane flying half way around the world you are bound to feel a little tired.
When your good friend doesn't even meet you at the airport and you have to catch a 2 hour train to get to her house your shoulders are bound to be tense from carrying your bags.
So the very least your friend should do when you finally arrive is let you have a lie in and then pamper you for the afternoon.
A real friend would not only pamper you but would join you in that fun and pampering so you feel right at home....
