Friendship

>>If you toss and you turn and you just can't fall asleep
>>You can count on me
>>You'll always have my shoulder when you cry
>>Cause that's what friends are supposed to do
>>I'll sail the world to find you



The friendship is very important, imagine if you toss and you turn and you just can't fall asleep and you have one person to share your bed, and this person say to you can count on me, this is a good relation, is a very good friendship. 
Imagine after that you can tell to this person you'll always have my shoulder when you cry when you pass bad moments, or I'll sail the world to find you, that means you gave your friendship at this person, because that's what friends are supposed to do, help each other.
