My brother and I recently had to sell a house and he dealt with everything. I'm so lucky to have a brother I can rely on and who I know won't try and con me.
We did and he was so precise with who got what and made sure he sent me my share quickly. He's such a neat brother in so many regards. I always know he'll be there for anyone who needs help.
We weren't always close. When we were kids we were always fighting. It wasn't until we got older that we got closer. We're best of friends now.
Don't be! There are many, many types of relationships and I don't think ours is necessarily typical. It's just the way it is :)
