Honestly, I don't believe in love at first sight, so I'm definitely biased there. But I do believe in true love...
Here's how I see it, two people see each other, and become infatuated with each other. They like the way the look, or like their mental assessment of the other person... Because total strangers really know nothing about each other, I don't believe they can be in 'true love' at first sight. I think of true love as an elderly couple, who's eyes shine when they look at each other. I've met some people like this, and when I come into the room I can just see how the love is shining out of their faces.... anyway.... (br/)
I believe true love is something that people have to work at over the years. I don't think it just happens instantaneously. Even those old couples had arguments with each other, and got better at understanding each other with time... It just doesn't make sense to me that two complete strangers could fall as deeply in love as those older folks are at first sight... but, I suppose it's always possible... and by no means take my answer as the only right one! I think this is largely a matter of opinion.... and, well, that was mine.
