But sometimes situations arise when a Big and a Little aren't matched very well. I've seen that happen, and in that case, I think it's fine if a Big/Little adopts another one. It seems kind of rude, though, to just switch...I mean, if I didn't have time for my Big or Little, or didn't really have much in common with her, I wouldn't mind if she were adopted by someone else but if she just cut me off I'd be kind of upset!
