They feel inferior

Depends on the circumstances
Crying largely depends on the circumstances of a person. If a person is brought up in a tough environment under poor conditions and is used to living a hard life, they might not be easily affected by things that usually make people cry.
They want to appear strong
Some people hold back their tears so they appear strong to the people around them such as a sick family member.
They’re hiding their emotions
Some people are used to hiding their emotions and suppressing them for a long time, which prevents them from crying. (See Why do people hide emotional pain?)
It depends on social factors
Most men around the world are brought up to believe that crying is not manly and thus they should never do it.
They don’t want to cry in public
Some people prefer to cry when they are alone, which can make it seem like they never cry.
It’s a genetic disorder
A genetic disorder called Congenital Insensitivity to Pain with Anhidrosis makes a person have high tolerance for pain, which is why they may not cry when they are subjected to severe physical trauma, for example.
It’s a rare syndrome
People suffering from a rare condition called Familial Dysautonomia (FD), or Riley-Day Syndrome don’t have the necessary reflex to form tears, which results in crying without tears.
Dry eye syndrome
Some people may have dry eye syndrome which can occur due to a number of reasons such as contact lenses, LASIK eye surgery and diabetes.
It’s an autoimmune disease
Some people may suffer from an autoimmune disease called Sjögren’s syndrome which affects glands that produce moisture in the body such as tear ducts. (See Why do we feel better after crying?)
