Humans tend to demand the environment to suit themselves. If not
it doesn't suit them, it's a tough time to go through.
Not surprised when a friend wants the attention needed but not met.
And ended up a sour relationship.
One could also fall in the trap of insensitivity towards people
around.
Nothing wrong with that just got to learn awareness.
Life is a cycle. When you criticise others. Sometime in your life,
you'll do the same and be criticised.
