In reality, you're just separate people who have ended up living in the same house via no fault of your own, which may make things hard. Shared parents, living spaces, and resentful Christmas photos do not guarantee or even imply that your sibling relationships will or should be close. They simply mean that you're stuck with each other. However, if the siblings are lucky enough to have good relationships with their parents, then there's a chance they can stay close despite being separated by distance and having different lives. It all depends on how much they want to be together versus how much they need to go their own ways. For example, if one brother is out traveling the world while another stays at home with the family business to keep it going, then they're probably not going to be seeing much of each other unless they set aside time to hang out. On the other hand, if both brothers work at the same company but from different locations, then they might end up working together more often than not because they need each other's help with important projects. The important thing is that they express an interest in getting to know each other again after so many years apart, and their parents understand that they don't want to be forced into sharing them. If they can figure out what kind of relationship they want, and if their families can accept it, then they've got a great chance of staying connected.
