I do believe in love at first sight, yet , I do not believe "live" at first sight. So if you love a person, you had better learn how to get along well with the person you love.  That is a sort of art that not everyone is good at.

Yes, love at first slight happens to some people but not all. If you can, you believe that depends upon you. 

I beleive it. Some people you have known them many years, but they are alike strangers to you. Some people you only know them for a few seconds, but it seems that you have known them for many years.Sometimes the relationship between people is mysterious.We explain it "Yuan feng"  in Chinese.

love needs time.

I do not believe in such a thing as "love at first sight" because I don't think love is something you obtain, but rather something that grows. Love is a deep combination of multiple feelings which develop as you spend more time with somebody or with something. It's not just a desire for something; it's a dedication of your time and resources towards something. Somebody who loves money doesnt just pick up a dollar bill and say "hey this stuff is pretty neat. I'm gonna devote all my time and energy to it". They spend enough time aquiring it to have them come to the decision that doing so will make them happy and be worth their efforts.
