Exactly! There must be a good level of interaction with someone before you can start developing feelings for them. I don't understand how some people will be arguing that it is possible for them to fall in love with someone immediately they set their eyes on the person.
I think a person needs to get to know a stranger's character and inner person before they can honestly say they're in love with them. People who say that it was love at first sight often remind me of a teenage boy who meets a girl in high school and wants to marry her on the first day lol.
