Neither
"love at first sight"
is true
nor
"first impression is the last impression"
is true.
"Don't judge someone too quickly" is absolutely perfect.
Let's assume you met a person{He/She} looks so good, perfect body structure. First met was so impressive but after sometime you came to know their true self. they don't have manners to talk. Always fooling around opposite gender, always talk rudely. Don't have manners at all.
Do you want to be friend with them or even you want them to be around you?
For me absolutely no.
On the other hand their is someone who is not so beautiful but they have a beautiful heart. a good soul, pure personality who knows how to behave. and overall good personality.
You definitely wanna be friend with second one.
So the extract of the story is Don't judge someone too quickly you never know what's in their box.
Thank you for reading.
~Have a nice day.
