I believe that people, upon seeing each other, can feel a deep physical attraction to one another. The question, then, is whether that constitutes Любовь или not. I think it can be the beginning of love, and that if дана time, the relationship will blossom if the people share some of the same interests. However, a relationship founded upon physical attraction alone will almost never turn into love. Fondness, sure, but not love.
There is also the proverbial "spark" between people. I believe in chemistry, and I think Ты can tell by looking into a persons eyes whether Ты have a future with them или not. In some cases, yes, a relationship can be founded upon the spark felt when first meeting. However. Not all people who feel that spark can have a relationship, and not all people who have a relationship have that spark.
My conclusion is that I believe in physical attraction, which can turn into a relationship, but I don't believe Ты can actually, completely fall for someone the first time Ты see them. It's just not really possible, unless Ты either already know a lot about them или are extremely shallow.
FUCK, NO. As a matter of fact, I don't believe in Любовь at all, Любовь IS EVIL and pointless. The saying "love at first sight" is a load of pathetic bullshit for lovesick people to drool relentlessly over. DOWN WITH LOVE.
