Hey, how's it goin'?
I am an only child. That is probably not surprising, but remains true regardless.
So, yeah, I don't have much experience with siblings, with or without tails. Although, I know a great many people who have siblings. I have never especially wanted siblings, but I can see how they might be useful.
Because that's what Sophie and I do: evaluate people's usefulness to us and then we like them based on said utility.
Etsy: the ultimate in utility.
Somewhat useful: Tumblr, Facebook, and Twitter.
