The only siblings I have are half-siblings. My nuclear family would have been an extra-suffocating threesome. Instead, I have an interesting brother and sister, in-laws, and darling nephews.
In my situation, every time I write a sentence, I'm thinking not only of the people I ended up in college with but my siblings, my family, my school friends, the people from my neighborhood. I've come to realize that this is an advantage, really: it keeps you on your toes.
I had a really wonderful upbringing. We were a tight family. It was wonderful to grow up with so many siblings. We were all just a year or two apart, and we were always so supportive of each other. I learned everything from my older brother and sister and taught it to my younger sisters.
When I was growing up, my mother was always a friend to my siblings and me (in addition to being all the other things a mom is), and I was always grateful for that because I knew she was someone I could talk to and joke with, and argue with and that nothing would ever harm that friendship.
I had an older brother, an older sister and a younger brother, and though I look back fondly on my childhood, I think that when you've got four siblings sharing the same resources and a single kids' bathroom, it's going to get a little tense at times.
