Essays / About how "honesty is the best policy" is not always true. Help me get started T.T [2]

I'm trying to write a 3 page essay for school.

My topic is about how "honesty is the best policy" is not always true,
for example, you tell "white lies" when you say your friend's shirt looks good on them,
even though it really doesn't.

I desperately need help catching a "hook" to start this essay.

PLEASE HELP!!!
thank you
