Parents are the most unconditionally caring and loving people in your life.
Most of their decisions will always regard your well being. They're the best guides!
However, they're human too. They can misinterpret your situation sometimes.
Their decisions then may not be in your best interest and probably not very appropriate. Yes, they can go wrong.
But there's always a guarentee. The guarentee that even if they faulter, they'll rush to pull you up and make everything perfect for you again!
