We live in an imperfect world with imperfect people, things do not always follow the ordered pattern.
People will not always meet your expectations, learn to accommodate.
People will not always understand and be sensitive to your situation, learn to be patient.
People will mostly treat you based on their interest, not to meet your needs, learn to work for yourself.
The best way to deal with people and situations you have no control is patient but prudent accommodation.
Tolerance is not a weakness, but a strategy to keep yourself from avoidable hurts and disappointments.
Learn to torelate patiently and prudently.
