If you're three years old and you've spent the entire summer playing with your older sisters, the first day of school is a rude awakening!
Big sisters pack up their backpacks, march out the door in their fancy new sneakers, brag about getting to see old friends and make new ones, and you're left behind with Mama.
I've got one sister and we're friends now, but we sure fought growing up. I remember my mom saying one time as she was almost in tears, "You girls are going to give me a nervous breakdown!" That shut us right up. Until the next day when my sister hid my favorite Barbie doll in the freezer and then it was on.
It turns out, sibling tension can be a good thing. Do tell!
