Do you live with the saying "First impression last?"  

First Impression is the last impression is partially true with me. Although First impression makes lots of impact on one's way of perception a lot.
i believe that if spend enough with that person, later you might come to know that all your first perception was wrong.
But this saying is correct for parties and big function, where we normally say hi and hello only to each other. in this case, your first impression matters a lot.

Generally we can study about the person from the first meeting itself. So we have some understanding about the person in our innerconsciousness. All further happenings will be controlled by this innerconsciousness. So in most of the cases the "first impression last"

I believe that in most cases, the first impression that I have for the person will last. It will last until the day that I will know more about that person before the first impression will be changed. It is true to most of us. I had experiences about people and the first impression will be there for some time. It may be risky to believe the first impression and we should be cautious and be patient to know some other details before we make a final decision whether the first impression is true or false. Good day.

according to my observation i think the impression i took from the person after 1st meeting is also the last impression, i can never judge people by only having 1st look of them for having som impression a sitting is required for me or at least just hello ic enough for having som impression for particular person

Yes...
I judge them with first meeting itself And in most cases it was correct.
If they talk for 5 miniutes means i can judge thier life style.

Hi care!
I do not enitrely go by the dictum that 'First impression is the last impression'. Sometimes, our calculation may go wrong. It would be better to frame a opinion about a person, only when we have met him/her for 3-4 times.
