Be thankful.

When people are good to you, treat you as a friend - it's because they want to. They don't owe you anything.

Don't abuse that. Don't assume that I can accept everything that you do and say.

Don't come running round only when you need a listening ear to your complaints, a sympathetic shoulder for your tears. Don't come running here for advice when you have defences, "i already"s and "buts" for every solution we come up with.

I care for you as my friend, but i am sick and tired of all this.

With rodents gnawing at it all the time, even the thickest rope will break one day.
