They have 3 Legs

 You see a person who got 3 legs before?
 I am sure you saw them before,
 Because they are around us.
 Now,
 You know who are them?
 They are BLIND.
 They can't see anything without black or white colour.
 How was they world?
 Only they know.
 Everytime I saw them,
 I will feel that they are the person who can face their life
 When facing trouble.
 They can't see anything,
 They just use another "leg" to help them see their life.
 I always admire them because they never give up their life.
 Sometimes,
 I will think about myself.
 If I become blind,
 then what should I do.
 All the things that I see is that on BLACK / WHITE colour.
 I think the first thing that I do after I become blind is 
 try to give up  My life.
 They are Blind.
 BUT
 They are brave.
 They persist.
 They try.
 They NEVER GIVE UP.
