it is possible to like at first sight.
but whether they continue to like each other, depends
on what they see as they get to noe each other better.
the longer you are with a person, the more is revealed and the
harder it becomes to hide things. they might be things that a
person might not be proud of and doesn't want to show at the
start.
I believe the ideal relationship is where both parties
are honest with and respect each other, and inspire each other to
be better people than they would have been when they were on their
own.
