The message of the story is not to judge people according to the initial impression זה נכון לכתוב ככה?

אולי initial תחליפי לfirst impression

תחליפי את the message ל the moral
ואת initial לfirst

the moral of the story is not to judge ppl. right away/ on first impressions
"the moral of the story is..:"looks can be decieving
"don't judge a book by its cover"
**********
אומרים גם first impressions matter..
