Being "Childish"

I mentioned Friendly's Request to the store manager. The SM agreed that we needed a little time before we could let the employee transfer stores, but she wasn't happy about how Friendly is doing things. The SM had already heard about the employee being fired (a story in and of itself) from another SM but had heard that the regional manager told Friendly to look OUTSIDE the company for a replacement. Interesting. {Yes, there's a lot of talking in my company. Since the office doesn't tell us much, we have to hear stuff from other stores. Knowing stuff before the office tells us is absolutely necessary, since they don't tell us stuff until too late to do much about it.}

Further, the SM thinks Friendly is being "childish" by calling to talk to me about it instead of the SM. I don't understand why the SM is upset. Besides the SM being off yesterday when Friendly called, Friendly knows and has worked with ME, not the store manager. She wasn't calling to officially ask for the employee; she was calling to inquire about the possibility of a transfer in the future. I didn't see it as childish. I could understand the SM being upset if Friendly was asking me in an official way or if we were trying to keep it a secret from the SM. But it was just an inquiry! Then again, we are quite a bit younger than the SM. Perhaps she's seeing something that we aren't. Anyone out there in internet land understand SM's perspective and care to explain it to me?
