Most of us can see. We can see what's in front, what's behind, and what's around. Some people can "see" what they don't literally see; they notice things other people don't. Some people, especially the nature-loving ones, see everything as a little more than what meets the eye, literally.
There is a group of people who can only see one thing: Themselves. Right in front of them, they've placed a mirror. These people observe everything they themselves do. They reflect, and they realise that they are so awesome, or they are so mean. But due to this mirror they have put in front of them, they cannot see any other person. They are too self-engaged, and too self-centered. Everything becomes "me", "me", "me".
"I am sad, so you should pity me."
"I am angry, so you should calm me down."
"I am a sensitive person, so you have to try and read my mind."
"I don't like David, so i'm not going out with you since david is tagging along."
"I love Alice, so i'm just going to hang out with her and forget about you."
"I am so pitiful. Shower me with attention please."
As much as i empathise with you, there is a limit.
Break the mirror and look around you, and notice that you are not the only one suffering.
Spare a thought for others.
