ulcer = broken friendship

Description:
A mouth ulcer is a painful open sore inside the mouth caused by a break in the mucous membrane.
Mouth ulcers often begin with a tingling or burning sensation at the site of the future sore. In a few days they often progress to form a red spot or bump, followed by an open ulcer.
Signs & Symptoms:
The mouth ulcer appears as a white or yellow oval with an inflamed red border. The grey, white, or yellow coloured area within the red boundary is due to the formation of layers of fibrin, a protein involved in the clotting of blood. The ulcer, which itself is often extremely painful when agitated, may be accompanied by a painful swelling of the lymph nodes.
Mouth ulcers are classified according to the diameter of the lesion. Minor ulcers, the most frequent type, are less than 10mm in diameter and typically heal in 1-2 weeks without scarring. Major ulcers are greater than 10mm in diameter and are incredibly painful. They usually take more than a month to heal and frequently leave a scar.
Causes:
The exact cause of mouth ulcers is unknown, but factors that appear to provoke them include stress, fatigue, illness, injury from accidental biting, hormonal changes, menstruation.

This is a the definition of an oral ulcer. I thought it matches the descriptions of a relationship as well.
Broken friendships started off with the MOUTH speaking the wrong words. Then this painful burning sensation in you grows and remains there.
The sore inside, worsen and swell up when you're frustrated.
small quarrels wont last, but serious ones will. and they do, leave a scar behind, forming a boundary between you and your friend.
We always think that our friend is in the wrong. but in actual, is that true? are you sure? well, probably school stress, other relationships and pms are affecting your mood and attitude.
Hmm. so whats the conclusion?
An excruciating pain.
