Hmm, I'm inclined to agree with Bryony- While I certainly believe in attraction or lust at first site, I don't think you know if it's going to be love or not until you get to know each other better!
No. There are cases when people have met and said they fell in love at first sight, but I don't believe it was true love until they actually got to know each other. It could easily have been the case that that person they felt head over heels for on sight turned out to be a complete jerk, or simply not compatible. I just happened to be the case that after getting to know each other, they were a great match.
I think there is love at first sight, not in the sense that people just automatically know they will be together forever. But love at first sight as in, they looked at the person and knew that they would fall in love with them. I knew a couple, when they went on their first date the man said to the woman, "I'm going to marry you" and they ended up getting married and are still together thirty years later.
Unfortunately not, not love at first sight. I believe liking someone upon meeting them, but not love as I believe love is a combination of many things that you can't possibly know just by looking at them. Some people have perhaps got lucky by seeing someone they like and then it turning into love, but I am not one of those people.
No, I think it's a bit juvenile, but love after five minutes definitely. Once you begin talking to someone and discussing things, I think you can easily gather whether you're going to get along or not. Love, however, takes time.
There's a big difference between attraction and love. I know a couple who didn't particularly like each other when they first met but after knowing each other for a while, they realised that they had a lot in common. They have been married for about five years now. Love is something that grows over time.
