For some people, the first person they call after a breakup, embarrassing mistake, family argument or major life decision is not a parent. It is their brother or sister. They may love their parents deeply, respect them and depend on them, yet still feel that a sibling is easier to talk to, confide in and trust. Psychology suggests that this does not necessarily mean they are closer to their siblings in every way. Instead, the sibling relationship can provide a particular kind of emotional safety built through shared experiences, similar life stages and a sense of being understood without explanation.
