It's not a matter of ego. It's a matter of emotions, at least regarding what I'm talking about. I agree her behavior is far from perfect and she needs to make sure to be fair, but the amount of people ordering her to personally, privately genuinely love this kid as much as she does her own is ridiculous, not in the least because that's impossible to do on demand. I like some people better than others. I'm sure you do too. I love some members if my family more than others. Do I do it on purpose? No. It's just how I happen to feel, and I'm privately entitled to my emotions as long as I treat people fairly and don't let it seep into ill-based favoritism.

PS: thank you for being civil despite disagreeing with me.
