What's a good reason to give your child a sibling? (Besides having someone to play with) :)

Your child will have someone to talk to. It may seem like a simple reason but it's one of the most awesome reasons to have a sibling. You'll never be alone when you're down because you have someone to talk to, especially if you are not comfortable sharing with your parents. The older I get, I realise that I share and talk more to my siblings than I do my best friends, especially since all 3 of us are living in different continents (Australia, Asia and Europe). It's never lonely with siblings, that's reason enough :)
