Hi guys!
I don't have two (yet

) but I remember reading once, I don't know if it was these forums or another - that someone once responded to the "Are they real siblings?" question with the answer:
"Well they fight in the back seat, if that's what you mean..."
I've ALWAYS thought that was the best answer for that question... It's been in my think tank in case I ever do go for number 2 and am in that situation!
Reading your stories and responses made me think of it!
