An unfortunate part of our human nature is, once we’ve reached a conclusion about someone or something, we tend to seek out evidence to support that conclusion. We easily accept the “reminders” to harbor bad feelings towards someone, but are skeptical toward the things that might dampen that negativity.
When you find out you’re going to have kids, there are certain things you imagine. You imagine your child running, rough-housing, and saying those funny things kids say when they think they understand a concept more than they actually do. When you find out you’re having twins, that picture is multiplied. Not only do you look forward to when you can interact with your child, but you look forward to seeing them grow up together, play together and get in to mischief together.
You don’t really consider that things don’t always work out that way.
