It did not, at all. But I grew up in a family of multiple HG+ kids, and my partner is an only, so I think our expectations for parenting were either that this is just how kids are, or none at all (in the case of the spouse!).

From the perspective of being a sibling, I would say quite seriously that Tigerle brings up a valuable consideration, as my siblings have been my most important and most enduring peer relationships, not only for the usual sibling reasons, but as intellectual peers.

OTOH, my partner, who is at least HG, has created a network of satisfying relationships out of non-related peers, partly by having focal interests in common, and partly by being a generally very nice person. =)
