From a day to day basis, I have. Some days one of them is just on my bad side, and the other isn’t. They may be twins, but they have very different personalities.. which I think some people forget about twins. One of them is far more energetic and outgoing than the other, and sometimes I think that plays in his favor. Other times I think it plays against him. As for the long run, no, I’ve never played favorites. It could happen, but it hasn’t, yet.
