I often get the feeling that people think growing up in a big family is all bad. I won't go through all the reasons I hear on a regular basis; I'm sure you have also heard them.
I also won't go into whether or not it's socially and/or environmentally irresponsible to bring seven children into the world. No. Do not even try to go there, as anything you bring up at this point (when the seven children are already in the world) will essentially be a reason why I or any one of my six siblings should not be alive, and not only will I not tolerate any suggestion along those lines, it's just a completely moot point. My parents are done having kids. It's irrelevant to pretty much everything whether they should have had as many as they did or not. Feel free to discuss that--elsewhere.
I would like to walk you through a thought experiment. Pick your favorite sibling; if you do not get along with your siblings or are an only child, think of your best friend.
Think about that person for a moment.
Think about how you have fun with them, how you can laugh yourself silly over nothing at all, how you think of them at random times because you heard a song on the radio or something, how you'd love to just drop everything to spend the whole day with them, how you know you can call them at 4 am if you need them, how they know everything about you and have been there your whole life, and if you ever needed a kidney they'd fucking tear theirs out with a spoon for you.
Think about that, and now think about the fact that I have six people that fit that description. SIX. If I ever needed a kidney, I'd have six fucking kidneys lined up for me. If all six were a match for me, I would have six people fighting over who got to give me their kidney.
And every single one of them is different. I have a very special, very unique relationship with each one of my six siblings, and none of them in any way replace any of the others.
If I want to talk about children, there's a sister for that.
If I want to talk about sex, there are two sisters for that.
If I want to talk about snowboarding, there's a brother and two sisters for that.
If I want to talk about physics, there's a sister and a brother for that.
If I want to talk about sports, there's a sister and two brothers for that.
If I want to talk about young adult literature of the late 19th century, there's a sister for that.
I could go on forever.
