ive never understood people who ahve sibling troubles. i think its just because ive never had any.
i live with my younger brother, and we get along really nicely. my older brother lives a state up, with a family, and he's my best friend hands down.
i have 4 known sisters, contact with two, and i love them both very much.
although sibling problems arent uncommon. this thread is proof of that. my boyfriend absolutely despises his sister, and vice versa, but thats more of a religious thing.
