Answer:
be aware and proactive when we come across such people and situations in life.
Step-by-step explanation:
We often come across people and situations in life that seem all good and trustworthy when we look at them outwardly. These kind of situations and people have so much of joyful and infectious attractiveness with them, we constantly like and trust them at the first glance.
However, they can be deceptive at times. We must always be aware and proactive when we come across such people and situations in life. Appearance can be deceptive. What we see outwardly is not always what is on the inside.
Just like how the clerk was fooled in the story "Hack Driver" by a person who seemed so happy and cheerful, people and things that seem good and trustworthy outwardly could be dangerous. Afterall, 'all that glitters is not gold'.
