Priceless.

When a friend bought you something you really need or you really love, and they need to save their money to buy you that stuff, trust me. You are very very special to them.
When a friend mad at you when you did something inappropriate or wrong, they never really mad at you. Trust me, they're just too in love to let you be bad.
They don't buy your friendship. They know money can't buy them friends, so they put an effort. Also, no one will show that they are mad when they really don't, except they love you so much. For people like this, their friends and their love are beyond priceless.
