This might go one of two ways. It will be great and you'll grow closer and more bonded with your brother. Or things might go badly. I recommend giving this a fair shot and trying not to let your anxiety over being judged cloud anything. Go into it with honest intentions of building stronger family bonds. I think that is a beautiful thing to accomplish in today's busy and disconnected realities. Families should stay strong and he could end up being a major support for you, and you for him.
